That's the wealth distribution problem I was talking about. I bet many would rather do hiking, writing or going to the cinema if they were paid the same. And since their job is useless already, it wouldn't change much. It wouldn't actually be a loss for anyone compared to the situation now (modulo the price of the machines and their maintenance, which is much less than a cashier's salary). However, replacing them with machines and giving them less money is a win for the shareholders, and that's what counts most in our system.
