In order to have been a worker for at least 5 years in both systems and therefore have an informed opinion of the difference, you'd need to have been at least 25 by the collapse.

Tack 30 years into that and yeah, at youngest the people with the most informed opinion on which system they preferred are going to be old.

And if you think you had a better system that in the past and it got destroyed, feeling nostalgic isn't weird it's the most normal emotion possible.
