 Money builds status, and status is a fungible, kind of usable power. But in general, I find people do not change that much. Personality traits are very stable over your life. People with high dark triad traits, narcissism, macrivalinism, psychopathy, that stays very stable whether you're poor or rich. So don't worry too much about money corrupting you. For the most part, making more money will actually require you to do some virtuous things, become more disciplined, become more organized, wake up a little bit earlier, give up a little bit slower.
