~~tax~~ eat the rich.
governments taxed rich people before. it went away because money is power and the rich are in power, they simply decided not to anymore.
solving the problem involves socialism, as in rebuilding the system to impede this accumulation of wealth in the first place. and sometimes the deposition of these people.
taxes are a volatile stopgap solution that look leftist if you squint, but they will use violence if needed to undo that win whenever they feel like they need that money back. this WILL NOT solve the problem by itself.
