The problem is much bigger than the existence of these gig economy services. The deeper issue is that demand for unskilled labor has become weak enough that, for many people, this is their best option relative to their skill set. Working conditions are terrible, but I don't think it would be a good thing for the world if Uber and the rest of the gig economy services magically disappeared one day: it would simply put the drivers into a financial tailspin with no real chance of escape. Moreover, Uber and Lyft are in a race to the bottom in terms of prices, and neither can unilaterally raise driver wages without pushing riders to the other app. The global economic rat race to drive down prices is unrelenting.
I suspect that universal basic income will become extremely popular in the public view, bordering on necessity, to offset the rise in inequality in the United States.
