You are able to negotiate with Uber, because they do not have an unlimited pool of labor to draw from. In labor markets with little to no regulations, wages can rapidly grow, because employers complete for workers, and that means they have to offer more pay when general productivity rises. Now what if productivity doesn't rise. Do we want to force companies to reduce shareholder profits in order to pay workers more than what the unrestricted actions of people in the market would result in them being paid? No we don't, and if you doubt me, I can link to you the economic explanations for why that is, which includes an explanation of the role that the profit earned by investors plays in increasing productivity and wages.
