Nothing you're saying is incorrect, but the underlying problem is that Uber drivers provide a needed service with a market and are not being compensated properly, and this goes for a lot of the gig economy. We can argue all day about this but I don't think it's unreasonable for people who provide a service that people want to demand in exchange a livable wage for their work, regardless of what the work happens to be.
There's been a trend in our society the last 30 years or so that paints a picture of everyone who does manual labor for a living as being a lesser person, and it's damaging us. Yes, automation will save us from a lot of our current burdens but we're not there yet, and until we are we still need people to unclog our drains, pave our streets and maintain the sewers. It's not glamorous and not skilled but it is desperately needed, and we can't just say "well low wages come with shitty jobs" and walk away like not having garbagemen is an option.
