They can find work elsewhere then?

Unless you are entrepreneur with access to capital, I'm not sure how you can expect individuals to will a good employer into being if none is to be found. Using the government to create better conditions for the working class is a completely reasonable use of the political process.

Why aren't they doing that already?

Because Uber is easier.

Didn't we already go through this line of reasoning during the industrial revolution? Didn't we already have our muckraking moments to show exactly why this line of reasoning is full of assumptions, totally devoid and dissociated from the actual reality of people's lives?

Where do people go if Uber does not exist?

You literally just linked a craigslist job listing to show indeed that uber is just a choice and they can take great jobs elsewhere.

Given that the industrial revolution in retrospect has clearly improved the lot of the entire world, comparing uber to the capitalists of the industrial revolution in attempt to castigate them is actually quite laughable.

Those industrialist were doing a great job of putting children in factories!

Before that, children (and their families) were doing backbreaking labour on farms. At least the factories paid better.

Yes, and they were also being exploited under feudal lords. I would hope we can make some kind of progress as a society beyond fuedal times.
