Earlier quoted context omitted.
One difference would be that Uber wouldn't be taking a 20% cut of the money involved. That 20% is what people believe pays for the benefits Uber ought to be providing.
That surplus wouldn't go entirely to the driver. Competition would drive down prices. Drivers will make more, but not the whole 20%.
I not sure that's true. The equilibrium price could actually be higher than where the market rate is now. Uber, Lyft, etc are subsidising their products with massive amounts of venture money in order to increase their market share - if they were removed from the equation it's entirely possible that drivers would get a higher fare and the cut Uber takes.
