If the company management runs a more efficient company, than they get more profits.. it just so happens that the rest of the "shareholders" are also the workers. I don't think it is right to look at the profit-sharing is not a "wage expenditure." Also, the desire to maximize short-term profits, as a traditional corporation with liquid equity is incentivized to do so, often leads to a lack of research, maintenance and other negligence that eventually adds up. The profit-sharing employees arguably have the long-term health of their source of income in mind and so they don't suffer the same tendency.
