In my life, I have met billionaires, working class people, hookers, gamblers, priests, judges, cops, thiefs... and I came to the conclusion that some people are good rich or poor or socially accpetable or not, some people have weaknesses that make then arseholes, some of them were even born evil...
but give a man power (a uniform, money...) and the later variety will become even more bastards. It's not money that makes people arseholes - it just gives them more power to be arseholes.
