Only if you believe in the Labor Theory of Value, which most don't. If I own a ship that's going on some expedition (as how shares originally started), I raise capital and reduce risk by issuing shares that people can buy. I have to, well, share my wealth but I have more money now to do the expedition. Corporations are just bigger versions of the same idea, they're still run by people, any of whom can decide not to work there anymore, for better or worse.
