No. The idea that a company is something you "own" rather than a group of people doing some kind of economic activity is a social construct, and one designed to disenfranchise the people doing the ongoing work. A company is a collection of assets and people - to own assets makes sense, to own other people's labour in an ongoing capacity does not.

I don't think he should - I think we should change the system that allows people to be worth billions off the backs of others. I don't want redistribution, I want reform.
