This was already "solved" in the 30-50s.

Anti-trust, effective taxation, and general social distrust of people who were creating wealth for themselves and not others.

obviously this sounds a lot like socialism (which its not, the USA in the 40s was not socialist.)

The issue is, discourse is being shaped by those who don't want things to change. Part of the reason why things changed is that lots of countries went through violent revolutions where the rich and powerful were ousted.
