The inalienable right to have a nice lawn

I keep trying to reconstruct the reasoning behind this:

Texas has long been a hotbed of controversy on immigration issues. And a proposed immigration bill in the Texas state House is sure to raise more than a few eyebrows. The bill would make hiring an "unauthorized alien" a crime punishable by up to two years in prison and a $10,000 fine, unless that is, they are hired to do household chores.

Yes, under the House Bill 2012 introduced by a tea party favorite state Rep. Debbie Riddle -- who's been saying for some time that she'd like to see Texas institute an Arizona-style immigration law -- hiring an undocumented maid, caretaker, lawnworker or any type of houseworker would be allowed. Why? As Texas state Rep. Aaron Pena, also a Republican, told CNN, without the exemption, "a large segment of the Texas population" would wind up in prison if the bill became law.

I would think that people could simply start doing without maids and gardeners. I had always assumed that undocumented domestic workers didn't have ironclad employment contracts.
