Then you'd have a point where tax = 100%, or at least where income after taxes doesn't increase with increase in income before taxes.

Thus you completely destroy the motivation of some very important enterpreneurs that just want to earn more than anyone. And they build their business somewhere else.

I agree with Jarek, plus there's a law of diminishing returns from wealth above a certain level. Look at people like Bill Gates, calling for higher taxation and distributing their wealth voluntarily because (i believe) they find their wealth level absurd. Wealth inequality is a mother of lots of evils, and taxation would be the easiest way to balance an economy, which in the end would benefit a capitalist society.

Examples of important entrepreneurs motivated solely, or even primarily, by earning more than anyone, please?
