Venture Capital is probably the best way to drain the billionaires. Those billions in capital weren’t wasted, that money just went to pay people who do actual work for a living. What good is all that money doing just sitting in some hedge fund account?
I don’t think it’s the best way out of all possible options. Even if it does “create jobs”, a lot of those jobs aren’t producing much of wider value, and most of the wealth stays in the hands of the ownership class. And a lot of the jobs are exploitive, like how “gig workers” are often treated.
Changes to tax law and enforcing anti-trust stuff would probably be more effective. We probably shouldn’t have bogus high finance shenanigans either. We definitely shouldn’t have billionaires.
