No offense, but while you're lambasting "garbage social conditioning" your perspective also reads as something from anti-work propaganda. Just look at how you contrast "productive work" and "leisure" with the latter being the more desirable end-goal.

I have a different take that doesn't necessarily put those in conflict. I think we are hardwired to have our status tied to our value to our tribe. When feel like we are no longer valued, our limbic system starts acting up. We feel anxious and stressed because our evolutionary brain is worried we'll get thrown out of the tribe. Unfortunately, in a modern society many have conflated value to mean a job. That's why I think some of those people who can retire continue to work. But the solution isn't to just replace "productive work" with more leisure time. I think that can also lead to bad outcomes when the other necessary parts of well-being are left unaddressed. I think people need* "productive work" that leads them to feel valued, but it doesn't have to be a wage/salary job.

* there's obviously large variance at the individual level, probably associated with certain personality traits. E.g., people who are high on the conscientiousness trait may need more industrious activities than others to have high levels of well-being
