As others have mentioned these workers have so little leverage right now because of the massive unemployment. So even if Amazon was to charge customers more, they could totally just pocket the money and the warehouse/delivery/grocery people would have no position.
It's so completely unfair. Everyone risking their lives to feed us right now should probably be making 2-3x normal pay (and we should be paying a lot more for their services).
Amazon should do what's good for the most amount of people which is keeping prices down. There are plenty of people willing to take these jobs, we have record unemployment. Raising wage 2-3x the normal pay is unfair given how many people would take these jobs today.
I think it's way to easy for us with nice paying jobs, and secure employment to say that we'd pay more for goods and services. There are so many unemployed people that aren't going to be doing good in a month. These people will want any job and will need cheap goods.
If we're going to do some sort of hero compensation for all of our essential works, which I'm in favor of, it should be through the government. Private sector should continue to be fair and act rationally.
