Yeah, I really can't fault people for thinking Uber is sort of a Trojan horse fucking up labor law protection. The Uber model also exists in food delivery, and that's pretty much what it is : bypassing labor law to create precapitalists daily workers.
Now I've heard exactly the same thing as everyone else : An Uber ride is often less expensive, more pleasant, easily found and as effective as a taxi one. It's a pretty logical development of instant communication and a shrinking, ever fluid job market. And the regulated taxi license system always had his own flaws pretty consistently whether it's in Paris, France or Austin, TX. It can't just be wished away with more regulations, there's some core issues to adress.
