I know a banker who is communist. It does not mean that he behaves like a communist in his actions, but he does in his words. From my perspective, he takes the best (or the worst) of both worlds: the quality of life of a very rich man who can afford living in the most expensive places and whatever leisure he wants, and the ability to punch down on the "lesser" people around him from his morally higher stand-point. Never under-estimate people's hypocrisy and cognitive dissonance, especially when what is at stake is exerting power over other people's lives. One can always find a way to rationalize one's crappy behaviour to try to lower the cognitive dissonance after the fact.
