As long as things gradual enough, similar to Roman empire collapse, you wouldn't even recognize the collapse. Any change is seen as good or bad, only by the people who saw both ends of it and categorize the change as such.

That explains why the youth are always merrier than the older folks who have a bigger burden of mempries.
