Driving a taxi was horrible. Anyone that laments Uber has never driven a taxi.
Let's assume, for argument's sake, that this is true - labor laws and protections increase wages in aggregate enough to account for all the jobs that are abandoned because they are not profitable enough to pay the required wages. There's one more thing to consider in Uber's case - the regional availability for jobs. Can we assume that the low-skilled adequate-income jobs you create through labor laws would be concentrated in richer towns, richer neighbourhoods, where the industry and market can afford the higher wages? What about the poorer neighbourhoods/towns? Uber(well, taxi service) allows people there to take a job which might not be available to them otherwise, without moving to a different town/neighbourhood.
But hey, I got that hamburger faster and $1 off the delivery.
It's the same game they're playing with AirBnB, Uber, etc. Just openly break the law and subvert centuries of built up labor laws and protections we've created to make America into a livable society, just to profit a small minority of shareholders. The players are the American people, with no choice left but live with this system because more equitable uses of this capital aren't perceived to give investors "10x returns". There used to be an agreement in the US between Capital and Labor that struck a fair deal, and this agreement has fundamentally eroded. What benefits and rights that did still exist in jobs up to this point are gone for most people. The result is a zero sum game, where human suffering is converted to shareholder profits.
