We should eliminate the private property owning class entirely instead of stopping individuals from having more than one billion dollars.

The problem is with the infinite accumulation of capital, not individuals with obscene wealth. In reality billionaires have actually very little control over their capital, they basically must re-invest the vast majority of it into accumulating more capital, the private jets are just what they skim off the top.

Billion dollar companies aren’t own by single people anymore and never were. The CEO is beholden to their board of directors and, even more so, the investors, if they stop making more and more money then the investments go elsewhere.
