If you look at customers served by an occupation it's needlessly absurd to pay as little as possible when there is a hand full of staff making millions of units/day. It doesn't benefit the economy. Many if not most of these are factory jobs that are horrific to do while supper important for economy of scale but I think with some effort we could also make a difference between a truck driver moving goods for 10000 people vs 1 customer. Or a dishwasher in a soup kitchen serving 2000 people vs a small restaurant serving 30.

And maybe their workers will actually be engaged in their jobs. I am always confused when low-wage employers complain that none of their workers give a sh*t.
