You could peg the numbers to inflation.

Personally, I see a big benefit of a wealth tax being lowering wealth inequality; even if the money isn't actually used for anything useful. That would at least help prevent the ultra wealthy from being able to unilaterally ruin society.

I compare ultra wealthy to blackholes - overtime they accumulate more and more mass and reduce mass elsewhere. But even in nature we have Hawking radiation (which leads to black hole evaporation). So for me wealth taxation is similar like this slow black hole evaporation which seems fair.

They can't ruin society unilaterally, unless you're talking about Vladimir Putin, who can only do it because he's the head of an autocratic socialist state as well as potentially being the richest man in the world. But the rich bit isn't what does it.
