Every large company will squeeze every second of productivity out of a worker unless it’s forced not to.
The 8 hour work day was fought for by workers, the 5 day work week was fought for by workers, child labor laws were fought for by workers. These things required protests and often time violence to get, because companies were literally killing people through work until these things became labor law.
Removing labor protection does nothing but remove safety for workers and increase profits for corporations.
The free market doesn’t work and has never worked. Anyone who says otherwise is willfully ignorant of history and basic logical reasoning.
