"Every fool aspired to be a knave"

Today's excerpt from Charles  Mackay's  Extraordinary Popular Delusions and the Madness of Crowds quotes perhaps my favorite line about a time of bubbles, up to and including 2007.

Exchange Alley was in a fever of excitement. The Company's stock, which had been at a hundred and thirty the previous day, gradually rose to three hundred, and continued to rise with the most astonishing rapidity during the whole time that the bill in its several stages was under discussion. Mr. Walpole was almost the only statesman in the House who spoke out boldly against it. He warned them, in eloquent and solemn language, of the evils that would ensue. It countenanced, he said, "the dangerous practice of stockjobbing, and would divert the genius of the nation from trade and industry. It would hold out a dangerous lure to decoy the unwary to their ruin, by making them part with the earnings of their labour for a prospect of imaginary wealth." The great principle of the project was an evil of first-rate magnitude; it was to raise artificially the value of the stock, by exciting and keeping up a general infatuation, and by promising dividends out of funds which could never be adequate to the purpose. In a prophetic spirit he added, that if the plan succeeded, the directors would become masters of the government, form a new and absolute aristocracy in the kingdom, and control the resolutions of the legislature. If it failed, which he was convinced it would, the result would bring general discontent and ruin upon the country. Such would be the delusion, that when the evil day came, as come it would, the people would start up, as from a dream, and ask themselves if these things could have been true. All his eloquence was in vain. He was looked upon as a false prophet, or compared to the hoarse raven, croaking omens of evil. His friends, however, compared him to Cassandra, predicting evils which would only be believed when they came home to men's hearths, and stared them in the face at their own boards. Although, in former times, the House had listened with the utmost attention to every word that fell from his lips, the benches became deserted when it was known that he would speak on the South Sea question.

The bill was two months in its progress through the House of Commons. During this time every exertion was made by the directors and their friends, and more especially by the Chairman, the noted Sir John Blunt, to raise the price of the stock. The most extravagant rumours were in circulation. Treaties between England and Spain were spoken of, whereby the latter was to grant a free trade to all her colonies; and the rich produce of the mines of Potosi-la-Paz was to be brought to England until silver should become almost as plentiful as iron. For cotton and woollen goods, with which we could supply them in abundance, the dwellers in Mexico were to empty their golden mines. The company of merchants trading to the South Seas would be the richest the world ever saw, and every hundred pounds invested in it would produce hundreds per annum to the stockholder. At last the stock was raised by these means to near four hundred; but, after fluctuating a good deal, settled at three hundred and thirty, at which price it remained when the bill passed the Commons by a majority of 172 against 55.

It seemed at that time as if the whole nation had turned stockjobbers. Exchange Alley was every day blocked up by crowds, and Cornhill was impassable for the number of carriages. Everybody came to purchase stock. "Every fool aspired to be a knave." In the words of a ballad, published at the time, and sung about the streets, "A South Sea Ballad; or, Merry Remarks upon Exchange Alley Bubbles. To a new tune, called 'The Grand Elixir; or, the Philosopher's Stone Discovered.'"
