Gentrification is a real paradox, not just for large urban cities but small towns and suburbs, too.

It can happen fast and almost go under the radar. Growth for its own sake isn't always a great deal -- it can drive RE prices up and displace people. But since the US still has a lot of land *and a heavy reliance on the automobile*, our housing problems mostly go unnoticed. Sprawl is still seen as a viable option, even tho there's no comprehensive planning or land management involved.
