It's called the Laffer Curve, douche nozzles. If taxes are at zero, of course government gets nothing. If taxes are at 100%, government gets peanuts.
Why?
How many of you are willing to work?
Oops. I'm sorry, that sentence should be longer. How many of you are willing to work if you know that all the money you make will be forcefully taken from you?.
Yes, I know. If only the greedy rich would just give you all of their money so that you could afford another bag of cheetos. But it doesn't work like that. In the real world, people work to further their own self-interests. When that happens, something magical occurs. Those rich people start hiring. Then they start buying things, which leads to more jobs. They don't do that if taxes are at confiscatory rates.
