UPS has 400,000 employees. Autonomous driving would pay itself off very quickly even if one of uber's cars personally murdered every single UPS and FedEx employee. Of course, the issue at play isn't joblessness, but the lack of a safety net for when people lose their jobs. Still, in the u.s., very few people actually starve to death, even when unemployed.

Perhaps lack of health care will kill them all. But was their health care that good to begin with? Perhaps an actual solution for root problems is the better route.
