How many people do you personally know that make their living as an Uber driver? I don't mean pensioners making beer money, or people doing it as a side job, here.
I know one. He's been doing it for a year and half, or so. He doesn't own his car. he has to lease it on a weekly basis, and he's paying through the nose for the privilege. He's doing it because his credit is shit, and he has no savings to buy a car outright.
He's getting ahead, but if driver rates get cut, he'll be going right back to being a line cook.
