The most important point of taxing the top ~1% is to simply bring their wealth more in line with their contributions, and to reduce their outsized power on the political system. Jeff Bezos isn't "worth" a million times more than his warehouse workers, and he shouldn't have that kind of money either as a matter of principle, or as a matter of democratic power. It's not a matter of punishment, but a matter of ensuring a more just/meritocratic and free society.

The fact that the state can also use some of this money to help with the funding of social programs is a secondary benefit.
