You also need to learn some economics. There is substantial evidence and supporting theory to suggest that absolute material wealth (once it exceeds a certain level of basic needs) makes relatively little difference to quality of life. See the "Easterlin paradox". In particular, even if absolute material wealth does have some positive impact on quality of life, a culture that optimises solely for efficiency is almost certainly sub-optimal for quality of life. I bet if you search your own experience you will find times when you did something that you weren't good at (and could easily have been done better by someone else more specialised) and found that you enjoyed it. The feeling of achieving something new and different and surprising? That's called quality of life my friend..... and many nomads a few thousand years ago probably had just as much of it as we do today
