Amazon is paying above minimum wage already. What do you suggest they should be paid?
The problem, though, is that there are people who have never not had jobs who nonetheless have opinions on what the baseline job should be. Since they've never had to choose between food and a shitty job, they assume that they can solve the problem by just mandating jobs not be shitty.
Ironically, people who struggle with keeping a job -- are more likely to shoot themselves in the foot by supporting minimum wage increase.
Good luck getting a that kind of law passed in America though. Far too socialist.
