Uber drivers are scabs.
I've been reading that over in Europe masked men have attacked Uber drivers with brass knuckles and hammers. It's suspected that the attackers are taxi drivers.
I'd ask the Uber drivers: Aren't you really being violent when you unlawfully steal the livelihoods of other people, who are lawfully earning their bread and supporting their loved ones?
Is it reasonable for you to believe that you can do that without any consequences?
