A couple of thoughts:
1. There is not enough personal wealth to make much of a dent in our debt.
2. A wealth cap would be nice, say $100M, but I am not sure how that would work.
3. How do you differentiate between net worth and assets? A company owner may have a high net worth due to the valuation of their business.
4. AI is going create the necessity for a lot of interventions and may be the culprit that ultimately kills capitalism.
