So your point is, what exactly? That employers stopped providing benefits, set schedules, livable wages, and full-time jobs not because it was profitable for them, but because ahh...um, what? They didn't fire bad employees? Just punished everyone for some bad employees, forever? 

Your point is totally irrelevant to my comment about worker's rights. Bottom line is that employers, big and small, have learned ways to game the system and maximize profits at the expense of workers. Just as one small example, look up the massive exploitation of "unpaid interns" going on for the last few decades.
