Yes perhaps there should be wealth caps. Did Larry Page really do 5% of all that labor that made google as big as it is? And should a single company get so big and have so much power? Yes, I get that they took risks and invested early, and we shouldn't take away that type of incentive, but perhaps it should have caps, or an S curve tax schedule.

Google doesn't have much power. It can't arrest you or pass laws or vote. It just happens to produce a lot of profits for its shareholders (who are, overwhelmingly, average people with 401Ks) and a lot of profits means a big market cap.

If we need revenue to fund useful government programs, great, let's tax Larry. But I don't understand what problem is solved by expropriation qua expropriation.
