Looks like Henry Ford discovered that profit was affected by overworking. He was still maximizing that function, no?
Sometimes that function includes making the worker happier, but sometimes it is inversely related.
re: startups, my point was that they have near zero chance of succeeding against large incumbents by moving at a leisurely pace. Sure, great technologies can be invented slowly. But once great tech is given VC money, it's a race. That race has created such a lead between the US and every other country in the tech world.
