Why does Apple need to charge price stuff so high when the profits it makes is already more than what it can realistically spend on improving its investors happiness?

I would assume the management team at Apple finds their work highly fulfilling or they would have quit a long time ago (certainly they can afford to).

I'm merely pointing out that if you don't find 60h weeks at your job fulfilling, it doesn't make much sense to chase more work and more responsibilities when the marginal utility of a dollar is pretty shitty past ~$100k anyways.
