That's basic economics. Had you gone to a real school to study this stuff you might have realized it. Wealth is infinite, our capacity to generate it is limited. Your comment is no different than if somebody were to say there is a finite amount of kinetic energy in the universe. That's just not how it works
I know the wealthy aren't taking any resources from the rest of us. Wealthier in a position where they can create wealth at a higher and more effective rate. But interestingly enough that wealth creation actually benefits us and we make more than we would have as a result of it, not less
I'm afraid if you're poor it's your own damn fault you can't blame it on anyone else. You have every bit as much of potential to increase your wealth and become extremely wealthy as anyone else and if that was your primary focus in life you could certainly do that. While it takes a lot of work it's not terribly hard.
