I'm impressed that you're able to do a sociological study of "the others" as you drive through their neighborhoods, probably with your windows up and doors locked.

Non-snarkily, I think people are the same everywhere, mostly good and hard working with occasional cheating when they think they can get away with it. From my personal anecdata, I've seen both shady deplorable acts and admirable selfless acts from millionaires, middle class, working poor, and even from homeless people on the street.

I do think that the fact that poor people have to rely on help from their social network more often makes them more humble in general.
