One thing that has been accentuated over the past few decades is the idea that you are responsible for your success. When you were poor, lacked means, or didn't have a good job, it was because the god of fortune didn't smile on you. Only the fortunate experienced success.
Now only losers are broke and live in crap towns, and winners drive expensive cars. With this idea in mind, calling it crap towns becomes an attack on the people, rather then the town itself.
This idea is thoroughly explored in Alain de Botton's "Status Anxiety"
