This superb video drives a stake through the heart of the meme that progress always equals more and better jobs:
All this and a cast of cartoon chickens. This is where it very much becomes clear that we need to analyze second-order effects. The video just starts wondering about those at the end. If we get very good at producing cheaper products at the expense of more and more jobs, who will buy those products? Who will be able to afford them if there is a rising underclass of unemployed that has trouble getting food, let alone iPhones? Sure, the market may turn to higher luxury items such as increasingly tricked-out autonomous cars, that can be afforded by the 1% (or less) who own the companies, but this is an unstable dynamic, a vicious circle. What will terminate that runaway feedback loop?
