In most (maybe all) markets, there is not enough consumer demand at the prices that would be required to support a living wage for everyone for whom flexible ride-share driving is the most lucrative work readily available. Now, iff that's true, what should the legislature do? Prevent that work from being done at all? Ration the supply (medallions or companies refusing to let drivers choose when/if to work)? The people said no, including a lot of current ride-share drivers.

e.g. it is probably the case that loading garbage onto a truck doesn't require more skill/specialization than driving a car for hire

However, the overwhelmingly vast amount of people prefer to do the job that they can do while sitting down, in an air-conditioned vehicle, vs. the one they have to do surrounded by stinking detritus, outside in all weathers.

Based on my own prejudices, driving a car for hire sits in a relative sweet-spot of low skill, low physical demand, low discomfort. I agree there are undoubtedly personal safety factors that you're more exposed to than, say, flipping burgers at McDonalds.
