There are plenty of businesses making things that, if they stopped making them, would not stop the world from turning. The point is, it's a business, who is likely competing against many other businesses that would be all-to-happy to scoop up their market share. I don't agree that employees should be expected to consistently work more than 40 hours week after week. I do agree that when situations arise in business that requires full and focused effort of entire departments or the whole company, the managers/owners first better come to the employees, with hat-in-hand, and discuss why this is important for the company and the team before issuing their mandatory overtime decree.
