Well-intentioned (by some people, prob most people on HN) and not so well-intentioned (anti-competitive lobbying by taxis) efforts to make the relationship less "exploitative" are likely doing more harm than good.
What happens when the gov mandates all these extra benefits? "Drivers WILL earn more money!" The answer is some combination of: Uber becomes costlier, people take fewer rides (or growth is slower than it should be), and some people who are perfectly willing and able to drive right now are unable to do so. Or (if demand is more inelastic) a bunch of new drivers decide the new benefits make it worth entering the market, and not everyone who wants to drive can/people sit around idle, etc.
Either way, you're hurting consumers and many existing drivers.
