It’s not wages that are the problem, it’s compounding multi-generational wealth. It’s very easy for rich people to make their income zero.

Amen. Minimum wage was a good start, but it’s become a mere virtue signal for labor rights. I have no reason to believe a maximum wage wouldn’t function similarly. Furthermore, nominal sums are pretty meaningless with currency anyway. Inflation makes them irrelevant pretty quickly. Progressive tax and social subsidy is what works, historically.
