> In each case we do things better, they cost less, and we move on to the next problem and jobs open up there. The tricky part is the mechanism by which we chose the next problem. If everything that sustains people gets cheaper we can lower all the salaries. Working people can buy more than before but get a smaller slice of the total pie. All things combined there is more stuff to divide which allows us to create more wealth elsewhere. The pie as a whole determines what should be the next problem to attack. Imagine for laughs an utopia where no one works, we all get a nice house, a car, free food, energy/fuel, a phone, computer, tv, nice cloths, etc, etc, everything you want plus an allowance of 10 USD per week. Whatever problem the market attacks next there is no incentive to do something useful for humans.
