> What will the economy consist of when there are no more paychecks?

I’m suspecting something like Soylent Green, but perhaps with more proactive action taken to free up resources by removal of masses who are no longer producing enough value to justify their expenses.

Following up, I believe eventually it will all be replaced by something much more resembling feudal power. Where bound servants provide service labor in exchange for protection/survival. Something like fuedalism but without the agricultural focus of manorialism.
