Every minimum wage job I've ever worked has been some kind of psychological nonsense to go along with the crap work. Rules that no one follows, schedules that shift constantly so you can never have a routine, random and incomplete accountability statistics to try and push people to "do better", and it feels designed specifically to have a continually changing staff of minimum wage workers so they chances for benefits are as minimal as possible.
If we count also the profit, and the unpaid work of the men, women or people (family, institutions) in charge of care of workers, we have that we are being robbed and alienated from the fruit of our labor in more than one way, and it is the basis of the economic exchange.
