IMO it's a good example of where government regulations are needed (max hours for salaried workers, overtime rules for wage workers etc) because otherwise its a tragedy of the commons type of situation. If another business can (and will) exploit their workers, they will undercut you because their costs are lower so you either need to do the same or go out of business. It has to be an outside party that looks at that situation and realize that's not good long term and stops it because businesses won't.
