I think it happens naturally in many places because older people tend to look at their history with rose tinted glasses. You forget the bad parts and treasure the good parts (which is not a bad psychological coping mechanism in itself). Add to that that the current world looks more complex as it becomes harder to keep up with age.
We see that even in Western countries, where a sizable set of boomers want to restore the order of the good old 50 or 60ies and vote conservative or right wing populist parties..
The question is what do the younger generations think and what portion of the population they are.
