We've not had an economy that rewarded doing things people want or need within my lifetime. Possibly we never did

Wait, that doesn't make sense. Are you saying you don't want or need any man-made thing? I assure you, many, many people were rewarded for designing, building, and selling the things you need and want to live your modern life.

However, I think it’s true that many more people were rewarded (likely even more) for things that people do not want. Facebook, etc

Indeed I do need such things. The fact that reward does not accrue to those who provide it feels strange
