I don't trust anyone who says tax "companies" rather than "the rich". It's like universal income. If you're talking about taxing someone other than the rich, you are talking about taxing people who can't afford it. If you're talking about giving money to someone other than the poor, you're talking about giving money to people who don't need it. Not everything that is counter-intuitive is a deep insight.

Ah OK, taxing the living shit out of companies or the investors and giving that money to people who spend it immediately seems to me to have nothing to do with companies using their profits on buybacks or dividends. Even with more taxes, some companies are going to do well enough to have made more money than they know what to do with, and sometimes returning money to the investors is probably their best option.
