I realize the Fair Labor Standards Act of 1937 is considered anathema among libertarians and many owners of enterprises who employ low-wage workers, but I don't think you'll find many takers among populace at large. The "freedom" you are talking about is the freedom to take or leave work schedules we consider abusive today. If you want to go back to a world where employment means 12/7 or starve, you are free to campaign for the repeal all you like, though. Your senators' aides are standing by, call now. Meanwhile, I will be lobbying them to constrain your freedom a little more.
