Echo Park Gentrification Watch

While there is always room for the unique and the exceptionally good, Echo Park does not really need another restaurant. It definitely does not need another chain restaurant. And, above all, it does not need a Chipotle.

Before gentrification, Echo Park was primarily known as a Mexican neighborhood and this stretch of Sunset Boulevard has always offered a wealth of spots for burritos and agua fresca and Mexican pastries. These are mostly locally owned businesses and all have deep ties to the community and its culture. When well-funded, heavily marketed franchises move in, the existing businesses get hit from two sides: they lose customers to the new places and they see their rents go up.

I sometimes think the concept of cultural misappropriation is overused, but it's difficult to avoid in this particular case. A Mexican American community seeing its local dining scene being invaded by a trendy the corporate restaurant serving some consumer-research team's idea of Mexican food.

Part of the problem with discussing gentrifying neighborhoods is that, in the early stages, almost everyone is a winner. Crime goes down. Existing businesses start seeing more customers which leads to more hiring. Night life picks up and with it arts and culture. In almost every way, things have gotten better.

Then comes the phase where the original residents and businesses  start finding themselves forced out. Well established locally owned places find it difficult to compete against well financed operations with higher prices, larger capacity and much bigger marketing budgets. Apartment dwellers seee steady increases in rent.

A little later, the younger "creative class" types who started the process are forced out as well along with the independent shops and coffee houses that can no longer hold off the high end retail outlets eyeing their spots.

We are often told that you can't have the first part without the last, that simply stopping when things were good for everyone would violate some kind of natural law. This might be true, or it might be that there's a tremendous amount of money to be made in these last stages, and the people making that money are controlling the narrative.

The Twonky

This is not a good movie.

Despite an interesting filmmaker and a fun lead, it's difficult getting through this one in a single sitting.

It is, however of interest as probably the first demonic television set movie, a genre that would go on to include Poltergeist, Videodrome, and many less memorable efforts. Though the Twonky was not released until 1953, it was completed in '51, just four or five years after television became a national medium.

Particularly when you take into account the rollout schedule of stations, the speed with which TV became one of, if not the, dominant cultural and political force, and one of the dominant economic forces in the country is astounding. The revolution did not go unnoticed at the time. Writers and cultural critics penned any number of alarmist essays and stories. I suspect that no medium before or since has created quite as intense a feeling of anxiety.

The Republicans' 3 x 3 existential threat

I've argued previously that Donald Trump presents and existential threat to the Republican Party. I know this can sound overheated and perhaps even a bit crazy. There are few American institutions as long-standing and deeply entrenched as are the Democratic and Republican parties. Proposing that one of them might not be around 10 years from now beggars the imagination and if this story started and stopped with Donald Trump, it would be silly to suggest we were on the verge of  a political cataclysm.

But, just as Trump's rise did not occur in a vacuum, neither will his fall. We discussed earlier how Donald Trump has the power to drive a wedge between the Republican Party and a significant segment of its base [I wrote this before the departure of Steve Bannon. That may diminish Trump's ability to create this rift but I don't think it reduces the chances of the rift happening. – – M.P.]. This is the sort of thing that can profoundly damage a political party, possibly locking it into a minority status for a long time, but normally the wound would not be fatal. These, however, are not normal times.

The Republican Party of 2017 faces a unique combination of interrelated challenges, each of which is at a historic level and the combination of which would present an unprecedented threat to this or any US political party. The following list is not intended to be exhaustive, but it hits the main points.

The GOP currently has to deal with extraordinary political scandals, a stunningly unpopular agenda and daunting demographic trends. To keep things symmetric and easy to remember, let's break each one of these down to three components (keeping in mind that the list may change).


With the scandals:

1. Money – – Even with the most generous reading imaginable, there is no question that Trump has a decades long record of screwing people over, skirting the law, and dealing with disreputable and sometimes criminal elements. At least some of these dealings have been with the Russian mafia, oligarchs, and figures tied in with the Kremlin which leads us to…

2. The hacking of the election – – This one is also beyond dispute. It happened and it may have put Donald Trump into the White House. At this point, we have plenty of quid and plenty of quo; if Mueller can nail down pro, we will have a complete set.

3. And the cover-up – – As Josh Marshall and many others have pointed out, the phrase "it's not the crime; it's the cover-up" is almost never true. That said, coverups can provide tipping points and handholds for investigators, not to mention expanding the list of culprits.


With the agenda:

1. Health care – – By some standards the most unpopular major policy proposal in living memory that a party in power has invested so deeply in. Furthermore, the pushback against the initiative has essentially driven congressional Republicans into hiding from their own constituents for the past half year. As mentioned before, this has the potential to greatly undermine the relationship between GOP senators and representatives and the voters.

2. Tax cuts for the wealthy – – As said many times, Donald Trump has a gift for making the subtle plain, the plain obvious, and the obvious undeniable. In the past, Republicans were able to get a great deal of upward redistribution of the wealth past the voters through obfuscation and clever branding, but we have reached the point where simply calling something "tax reform" is no longer enough to sell tax proposals so regressive that even the majority of Republicans oppose them.

3. Immigration (subject to change) – – the race for third place in this list is fairly competitive (education seems to be coming up on the outside), but the administration's immigration policies (which are the direct result of decades of xenophobic propaganda from conservative media) have already done tremendous damage, caused great backlash, and are whitening the gap between the GOP and the Hispanic community, which leads us to…



Demographics:

As Lindsey Graham has observed, they simply are not making enough new old white men to keep the GOP's strategy going much longer, but the Trump era rebranding of the Republican Party only exacerbates the problems with women, young people, and pretty much anyone who isn't white.

Maybe I am missing a historical precedent here, but I can't think of another time that either the Democrats or the Republicans were this vulnerable on all three of these fronts. This does not mean that the party is doomed or even that, with the right breaks, it can't maintain a hold on some part of the government. What it does mean is that the institution is especially fragile at the moment. A mortal blow may not come, but we can no longer call it unthinkable.

There will be safe seats. There are no safe seats.

In 2017, we have a perfect example of when not to use static thinking and naïve extrapolation.

Not only are things changing rapidly, but, more importantly, there are a large number of entirely plausible scenarios that would radically reshape the political landscape and would undoubtedly interact in unpredictable ways. This is not "what if the ax falls?" speculation; if anything, have gotten to the point where the probability of at least one of these cataclysmic shifts happening is greater than the probability of none. And while we can't productively speculate on exactly how things will play out, we can say that the risks fall disproportionately on the Republicans.

Somewhat paradoxically, chaos and uncertainty can make certain strategic decisions easier. Under more normal (i.e. stable) circumstances it makes sense to expend little or no resources on unwinnable fights (or, conversely,  to spend considerable time and effort deciding what's winnable). The very concept of "unwinnable," however, is based on a whole string of assumptions, many of which we cannot make under the present conditions.

The optimal strategy under the circumstances for the Democrats is to field viable candidates for, if possible, every major 2018 race. This is based on the assumption not that every seat is winnable, but that no one can, at this point, say with a high level of confidence what the winnable seats are.

Though, to be perfectly fair, Tennessee has always been a hotbed of leftist radicals


We have all heard the statistics about how difficult it is for a Congressional representative to lose his or her job. This is partially because of things like gerrymandering and spigots of campaign cash, but it also reflects a process that does a pretty good job allowing a reasonably competent and dedicated legislator to keep the constituents fairly happy in his or her district. A big part of that process is the maintaining of good relationships and lines of communication with voters and communities. Many political career has ended when voters felt someone had "lost touch with the people back home."

In this context, stories like the following from Talking Points Memo's Allegra Kirkland take on a special significance.
Constituents requesting that Rep. Jimmy Duncan Jr. (R-TN) hold a town hall on repealing the Affordable Care Act aren't being met with a polite brushoff from staffers anymore. Instead, Duncan's office has started sending out a form letter telling them point-blank that he has no intention to hold any town hall meetings.

“I am not going to hold town hall meetings in this atmosphere, because they would very quickly turn into shouting opportunities for extremists, kooks and radicals,” the letter read, according to a copy obtained by the Maryville Daily Times. “Also, I do not intend to give more publicity to those on the far left who have so much hatred, anger and frustration in them.”

In the first weeks of the 115th Congress, elected officials dropping by their home districts were surprised to find town halls packed to the rafters with concerned constituents. Caught off guard and on camera, lawmakers were asked to defend President Donald Trump’s immigration policies and provide a timeline on repealing and replacing the Affordable Care Act.

Now, many of them are skipping out on these events entirely. Some have said large meetings are an ineffective format for addressing individual concerns. Many others have, like the President himself, dismissed those questioning their agenda as “paid protesters” or radical activists who could pose a physical threat.

Voters turning out to town halls are pushing back hard on this characterization, arguing that they represent varied ideological backgrounds and have diverse issues to raise. Constituents unable to meet with their elected officials over the weekend told TPM that they’re not attending town hall events to make trouble. Instead, they say they want accountability from the people they pay to represent them.

Kim Mattoch, a mother of three and event planner, told TPM that she tried to go to a Saturday town hall in Roseville, California with GOP Rep. Tom McClintock but couldn’t make it in. The 200-seat theater hosting the event was quickly filled to capacity, leaving hundreds waiting outside.

“I’m a constituent of McClintock and a registered Republican in a very Republican district—though I don’t really align very well these days with the Republican Party,” Mattoch said in a Monday phone call. “So I wanted to go to the town hall because I legitimately had questions for the congressman.”

Mattoch said the protesters waiting outside had a wide range of “legitimate concerns.” She personally hoped to ask her representative about how the GOP was progressing on repealing and replacing the ACA and why House Republicans last week voted to kill a ruling aimed at preventing coal mining debris from ending up in waterways.

Yet McClintock told the Los Angeles Times that he thought an “anarchist element” was present in the crowd outside his event, and said he was escorted to his car by police because he’d been told the atmosphere was “deteriorating.”

Ramon Fliek, who attended the McClintock event with his wife, told TPM on Monday that police “were kind enough to block the whole road” to make space for the overflow crowd, and that he overheard protesters thanking law enforcement for “doing their jobs.”

“If you look at the videos from the event, you can’t get any notion that it was aggressive,” he said. “There was an older woman with a poodle that ran after him and it’s like, okay, the older lady with the poodle is not going to threaten you. I understand that he might want to give that impression, but it was very pleasant.”
Admittedly, it is a long time until midterms, but possibly not long enough to repair this kind of damage.

Part of a wholesome breakfast

As with so many things, the late 19th and early 20th centuries seem to represent the turning point for a modern perspective on nutrition. As far as I can tell, this is the point at which people started thinking of nutrition as a chemistry problem: you take food into a laboratory, analyze the constituent parts, and optimize the things you need while minimizing the things you don't.




The thing that jumps out at the modern reader as particularly off key is the treatment of fiber. I'm assuming “crude” in this context means insoluble, but it is still odd to see fiber treated as an undesirable component.

When the NIMBYs were primarily motivated by racism and class bigotry, there was no NIMBY backlash. *

We've commented before that much of the discussion of urban density, particularly on the advocates' side, tends to be overly simplistic and inappropriately moralistic. This last point is greatly complicated by the fact that historically the motivations for NIMBYism were more often than not pretty repugnant. Opposition to public transportation, low-cost housing, and integration of neighborhoods was based almost entirely on the desire to keep people of color and the poor as far away as possible.

These issues haven't gone away, of course – – try to add another subway stop in Beverly Hills and check out the response you get – – but the NIMBY/YIMBY conflict that makes the news and dominates the public discourse here in Los Angeles (and, I suspect, in the Bay Area as well) has very little racial and class component.

At best, the battle over Santa Monica is a struggle between the top decile and the top quartile. Sometimes, there's not even that much of a class distinction. To be hammer blunt, you have a bunch of well-off people who enjoy the fantastic weather and bland conspicuous consumption of the town and who don't want other well-off people coming in and clogging the place up.

Advocates generally argue that development will drive down prices both in the city of Santa Monica and in the county of Los Angeles. I'm skeptical. While I'm not saying this is a bad approach in general, the arguments I've seen so far seem simplistic and overly linear, and the proposed impacts wildly overoptimistic. I could easily be wrong on these questions but either way, this is not a moral argument and framing it in moralistic terms simply serves to cloud the issues.

We won't even get into the return of vinyl...


I'm assuming that everyone has heard the buggy whip analogy, one of the most shopworn pieces of conventional business wisdom. One of the underlying assumptions, sometimes made explicit depending on who's doing the telling, is that you are always better off abandoning even the best company in a declining industry in order to make the move to a field that's new and growing.

It's important to note that even in declining industries you can find companies that continue to turn a profit for a long time while even in industries that do proved to be the wave of the future, lots of individual companies don't last that long.

Or, put another way, you can still buy a buggy whip from the Westfield Whip Manufacturing Company, but they stopped making Lamberts a long time ago.

The checkers speech was made in 1952.

I know you know that – – everyone knows that – – but think about the implications for a moment. This nationally televised speech is often credited with saving the career of Richard Nixon and making him one of the dominant forces in American politics for the next 20 years. It was unquestionably a turning point in the way that public figures used media, particularly in the face of scandal.

And it happened in 1952.

What's the big deal? Remember that television was still in its experimental phase until the postwar era. It wasn't until around 1947 that it became a national medium and even then, large swaths of the country had no TV stations. The fate of a presidential ticket was determined by something that was, at best, five years old.

When you hear the claim that technology today is changing our lives faster than ever before, remember Checkers.

All of this would look remarkably modern if not for the horse drawn carriages

What struck me about this 1903 cover from Scientific American was the way planners set aside dedicated spaces for different modes of travel, one  level for pedestrians, one for cyclists, one for automobiles and carriages, and two for trains, an allotment that would no doubt please many urbanists today.

This begs the question, did this approach to urban transportation fall out of fashion? Or was it one of those things that had a way of showing up in proposals but which seldom made it to the groundbreaking?

Seems like a good time to reopen this thread.

This post by Jonathan Chait about the renewed demographic threat faced by the GOP got me thinking about a thread I've been meaning to revisit.

For obvious reasons, the broadly liberal demographic trends in American politics have received much less attention since the 2016 election. Yet the fact remains that America is politically sorted by generations in a way it never has before. The oldest voters are the most conservative, white, and Republican, and the youngest voters the most liberal, racially diverse, and Democratic. There is absolutely no sign the dynamic is abating during the Trump years. If anything, it is accelerating.

The most recent Pew Research Survey has more detail about the generational divide. It shows that the old saw that young people would naturally grow more conservative as they age, or that their Democratic loyalties were an idiosyncratic response to Barack Obama’s unique personal appeal, has not held. Younger voters have distinctly more liberal views than older voters:

One could probably quibble with the overall definitions of which voters have liberal views and which have conservative views. What’s telling here is the comparison between generations. By Pew’s given definition, younger voters are wildly more liberal than older ones. The youngest voters have nearly five times as many voters with liberal views than with conservative views. The oldest voters have one and a half times more conservative than liberal voters.

Correspondingly, the Democratic lean of millennial voters is as strong as ever:

In the upcoming midterm elections, millennials are providing a huge share of the Democrats’ edge, with older generations splitting their vote relatively close:
In the first few months of the Trump administration, we did a series of posts on how the underlying dynamics of the Republican Party were changing and what some of the consequences might be. One of the fundamental ideas of the thread was that the country had entered a period where our normal ways of talking about subjective probability made no sense in terms of politics. You could still make directional and even ordinal statements, but we were so far outside of the range of data and precedent that you could no longer confidently assign upper and lower bounds to the probability of a number of events including the destruction of the Republican Party. Note, I never said that this was "likely" to happen, but rather you can't say that it can't happen now.

If I were writing this today, there are obviously things I would handle differently, but I'm reasonably comfortable standing by the main points.

I guess I'll force myself to have a chocolate malt

I'd like to see a list of all of the foods that were originally sold on the basis of health but which now survive as unhealthy indulgences.  In addition to malted milk, many early soft drinks fall into this category and I have the feeling I'm missing some other obvious examples.

Hyperloop watch -- We are now reaching that part of the movie where the wife goes to the bank and realizes that her husband has given their life savings to the con man.


I know I've been harping on this for years now and I'd imagine regular readers are growing a bit tired of the ranting, but the standard tech narrative, the one that is still more or less the default for even sober news organizations like the BBC and NPR, is deeply flawed and genuinely dangerous.

The hype and bullshit and magical heuristics that dominate our discussion of technology and innovation aren't just annoying; they have a real cost. They distort markets, spread misinformation, lead to bad public policy, and starve worthwhile initiatives of both funding and attention.

No figure brings out the worst of these tendencies in journalists more than does Elon Musk. Musk, it should be noted, does have some major accomplishments under his belt as an administrator, promoter, and finance guy. With SpaceX and, to a lesser degree, Tesla, he deserves considerable credit for significant innovations, but even with his most serious projects, there is always a bit of the Flimflam Man present.

The Hyperloop has always been Elon Musk at his most substance-free. A 70s era B- senior engineering project dressed up with 3-D graphics and a cool name. Despite being thoroughly demolished by virtually every independent expert in the field, the "proposal" has generated endless and endlessly credulous press coverage. Hundreds of millions of dollars in financing have been lined up by Hyperloop companies with dubious business plans. And now you can add millions in tax dollars to that.



From an excellent Slate article by Henry Grabar.


For American lawmakers, funding public transit often feels like small ball. Politicians prefer to dream bigger. Earlier this month, transportation agencies in the Cleveland region and in Illinois announced they would co-sponsor a $1.2 million study of a “hyperloop” connecting Cleveland to Chicago, cutting a 350-mile journey to just half an hour. It’s the fourth public study of the nonexistent transportation mode to be undertaken in the past three months.

“Ohio is defined by its history of innovation and adventure,” said Ohio Gov. John Kasich, who once canceled a $400 million Obama-era grant for high-speed rail in the state. “A hyperloop in Ohio would build upon that heritage.” In January, a bipartisan group of Rust Belt representatives wrote to President Trump to ask for $20 million in federal funding for a Hyperloop Transportation Initiative, a Department of Transportation division that would regulate and fund a travel mode with no proof of concept.

It’s hard to keep up: Last week, the Mid-Ohio Regional Planning Commission announced feasibility and environmental-impact studies for a different hyperloop route, connecting Pittsburgh and Chicago through Columbus, Ohio, to be run by a different company, Virgin Hyperloop One. The company—which fired a pod through a tube at 240 mph in December—is also studying routes in Missouri and Colorado.* Meanwhile, Elon Musk—who has obtained (contested) tunneling permission from Maryland Gov. Larry Hogan—pulled a permit from the District of Columbia for a future hyperloop station.

But let’s first look at the hyperloop [from our old friends, the incredibly flaky, Hyperloop Transportation Technologies -- MP] that Grace Gallucci, the head of the Cleveland regional planning association the Northeast Ohio Areawide Coordinating Agency (NOACA), told local radio could be running to Chicago in three to five years, and to the study of which the NOACA contributed $600,000.

Urban suburbs


My first corporate job also led to my first big move. I'd bounced around before that, between teaching and going off to grad school, but the moves had, at most, entailed crossing only one state line. The corporate position took me from just west of the Mississippi to the East Coast, with no social contacts or experience of the area to draw on.

I did what seemed like the sensible thing and got an apartment a few minutes from work. The company's campus was on the outskirts of town deep in the suburbs. Before that, I had lived in the country, small towns, and a couple of urban areas. Each of those three options had some strong pluses and, under the right conditions, could be quite appealing. By comparison, suburban living, at least without kids, had nothing to recommend it as far as I was concerned. I realized quickly but still too late that I should have picked an interesting neighborhood closer to the center of town, even though that would've meant an extra 20 or 30 minutes of commuting per day.

I did not repeat that mistake for my next job. Before moving, I scouted the area and ask around before deciding on a very cool neighborhood featuring lots of restaurants, bars, and the city's best art-house movie theater within easy walking distance. My daily commute was 45 minutes to an hour, but the traffic wasn't bad and much of it skirted around (and at one point across) the Chesapeake Bay making for a relaxing and scenic beginning and in to each workday.

That neighborhood was, for me, functioning as a de facto suburb. I was trading a longer commute for more desirable living conditions. The fact that these more desirable conditions were found in an area of higher density, rather than lower, does not affect the underlying dynamic.

One of the primary tenets of faith among utopian urbanists is that making it dense areas more dense will have a range of tremendously beneficial effects starting with great reductions in commuting and suburban sprawl. The existence of urban suburbs raises serious questions about that argument.

How big a deal is this? A good urban researcher could probably provide us with fairly reliable numbers, but we can say with some confidence that it's having a sizable effect in at least isolated cases. San Francisco has clearly become an urban suburb for Silicon Valley and, to a degree, Santa Monica and the rapidly gentrifying Venice Beach often fill the same role for much of Los Angeles.

It is worth noting that San Francisco followed by Santa Monica are probably the two cities that density proponents are most passionate about. This raises a disturbing question (and one which, I suspect, researchers will find more difficult to answer): if you greatly increase the density of cities that are already largely functioning as urban suburbs, will you in effect simply be producing more suburban sprawl?
