Also -- imagine what would happen if millions and millions of hard-working people in the suburbs decided to move to the city. Lots of gentrification (which is nice) but it comes with a downside: the poor folks in the cities would be pushed out. Where do they go? The suburbs? Now you have poor, uneducated people, with no jobs, no cars, living in the middle of nowhere. That's not going to fly.
A modern society with an underclass (which is what we have) needs the cities to hold that underclass. There's no other place to put them. And for the most part, hard-working people seem to prefer living amongst trees over living amongst the underclass.

We're seeing that here in DC- over the last decade or so the city has been getting gentrified and is now more white and richer. This has led to large numbers of poor black residents moving out to Prince George's County, which has seen a spike in crime.
This situation needs to sort itself out over the next decade- people need to figure out whether they can afford to keep living in the suburbs and commuting in to work. The only thing government should do is lay off on the restiction on oil drilling.
