I've said it before, and I'll say it again - if you were to pay for real cost of overhead and to pay the driver, you'd end up with a price that no customer is willing to pay.
Uber has briefly entered profitability, but only by absolutely shredding any pay to their drivers, who will jump ship eventually.
The reality is that once investors wake up and close their pockets, these companies vanish into dust. It's either that or their drivers will abandon them.
