There are literally entire regions in the rural US where the only place to work is Walmart because they came in and deliberately operated the store at a loss to kill off all surrounding businesses. What do you suggest those people do?
Not everybody can be a white collar worker either. There are also literally not enough well paying jobs to go around. You assume everybody has the ability to just quit and move on whenever they want. And I'm saying this from a comfortable position, career wise, much like you. I just know how shitty things are.
