That works both ways. There are plenty of dumba*s white trash parts of this town where all the same stuff is happening.
Throwing a curve ball (bell?) here, but living in a high IQ area also creates some problems, IMHO.
People in those areas are also insulated. They don't fully understand the nature of the problems of an inner city because they have trouble with the concept of a person who, for example, loots a store, then complains because the store closed down. The smart person is thinking, "If I want a store in the neighborhood, I'll make sure and buy things there so they'll stay." The looter thinks, "I want the stuff in that store." He will not consider that looting the store will make it close and he won't have a store in the neighborhood, because he doesn't think more than twenty seconds ahead. I call it "crapping on the floor then complaining there's crap on the floor."
So, the smart people continually propose and implement policies that will not work in a lower IQ population.
Side slide: when medical schools were admitting on GPA and IQ alone, they started having a problem that at a certain high level IQ, a lot of people started having trouble interacting with normal IQ people. I think Bobby Fischer is an example.
