Are you sure capital owners do not contribute to our states and financial systems?
For instance, Jeff Bezos is worth $238 billion even though Amazon has a $2.6 trillion market cap. That's $2.4 trillion of value created for other shareholders plus trillions more for employees, customers, suppliers, governments, and other stakeholders.
Jensen Huang is worth $164 billion while NVIDIA’s market cap is $5 trillion. That’s $4.8 trillion of value for other people (ignoring value created for non-equity stakeholders).
etc.
I'm not saying that there should not ALSO be other ways to force contribution (e.g. via taxes), but to say they do not contribute at all is false.
