This already happens, even for reasonable well paid workers. In LA, the average commute is over 45 minutes. I knew low wage workers who commuted 1.5-2 hours by bus to get to work. And it's been that way for decades. A study showed that a lot of people actually valued their (car) commutes, since it was the time they had to themselves. In the little town where I live now, I get mad if we can't park right in front of the place that I am trying to get. In San Francisco, you are lucky to get parking a few blocks away. I know fair bunch of people who want to have a house, and live in the Bay Area, but are cops, teachers, etc, so they have 1 h+ commutes on the train. Human beings are incredibly adaptable, and get used to inconvenience, or conversely, ease, very quickly. As long as the infrastructure doesn't break down catastrophically (say, by way of zombie apocalypse), we'll probably just keep on trucking along.
