My salary is negotiated on open, highly effective market. Share of my work that goes to the company shareholders represents their investment. If the company fails, I don't risk anything, but they will lose the money they put into the company in the first place. Naturally, if the company succeeds, they have to get capital gains on that investment. The fact that I will be able to get any salary from this company at all will be a direct consequence of a risk that they took upon themselves, not me.
