There might be a bit of that. 12 hour days are not unheard of in other parts of the country. Doctors in the ER can work even longer shifts (though obviously the stakes are incommensurate; still, I would contest the soundness of having tired doctors performing medical procedures). But there's also the question of whether it is truly necessary. Will hiring more workers to cover more shifts really increase production costs that much? If you're competing with cheap labor, possibly slave labor, then you have to look to other ways to push back, like fast tracking immigration of talent from places like Taiwan, imposing tariffs on imports from countries with cheap labor, investing in automation to reduce production time and costs, etc. Sometimes there isn't much you can do, but generally speaking, while private business is a good thing, it is also true that private business cannot contradict the common good. The idea that you can simply do whatever you want because you're private is simply nonsense.
