Now that you mention it, I see what you're saying. As if its illegal or even immoral to be rich. Heck, I strive for the day that I might be well off enough to not have to work again.
I think what's going on here is some serious stereotyping; i.e., if somebody has lots of money, they must be corrupt and even if they aren't, they don't deserve it and I want it and yadda-yadda...
