Sometimes, there are not.
It's the natural order of things to decay. Everything. Cultures and civilizations aren't immune and we have all of history to note this. We have more material wealth than any civilization in recorded history and we grow unhappier with each passing year and hopelessness and loneliness climbs and climbs. You certainly won't find solutions to that in public policy, so you can stop looking to politicians to fix these things. These problems transcend government or the free market.
