The problem with the current incarnation of capitalism is the assumption that goods and services will make people happy, and that their wants are intrinsic rather than indoctrinated. In truth both of these are false more often than not. Thus, while capitalism is very efficient, at this point that efficiency is mostly allowing us to crank up the speed setting on the hedonic treadmill, while we rack up debt, work soul crushing jobs and destroy our environment. This is sad, because in theory capitalism is awesome - we just need to stop letting the people with all the money write the rules of the game.

Robots are not the maximizers. People are at this point still driving the demand side of the equation, that's true, but there's not reason why they can't be replaced as well on that end.

The economy is a self-maximizer, bootstrapped on human labour. As automation progresses, it will become self-hosted.
