Are we really better off if Elon is allowed to own only a small fraction of Tesla and SpaceX? I worry this proposal has the potential to harm American competitiveness by forcing entrepreneurs out of the companies they start. The proposal also would target only American citizens, but if the goal is to fight inequality shouldn't we tax all mega corporations operating in the US even if the owners are foreign?
