How did Uber et al. offer services below cost until they'd driven out all competition? The property holdings are not these landlords' only source of income. Why would milk producers deliberately dump millions of gallons of milk (representing a commensurate amount of labor to both produce and then dispose of)? Because they've created an oversupply that threatens to destabilize the price.
The math works, it's just heinous.
I never understand why people think Uber is some kind of mic drop. I don't like Uber as a company, but Uber is vastly better than the system it replaced. It this a generational thing? Are the people casting Uber as archvillains just too young to remember not being able to get a cab at 9PM, or having their cabs kick them out halfway to their destination because they decided to go on a break?
