Well, the idea of generational theory is that we reinvent these systems, institutions and laws during a winter crisis as our previous ones all come crashing down, which we are going through right now. As for people that are naturally conservative or naturally liberal, I believe that they both play a crucial role in all of this. Liberals' purpose is to introduce positive ideas that will benefit society, conservatives' purpose is to reject negative ideas that will harm society, while centrists tend to support both sides specifically in ways they view beneficial. Neither role should be discredited or diminished as they both are valuable for society, but in completely different ways.
This is true. However, society's four turnings actively reflect a human life and I don't think that it's coincidental that both last roughly ~80 years. Society eroding and reinventing itself every ~80 years makes sense as it is in tune with the average life span. I also agree that we all go through our own winter, fall, spring and summer seasons in our own life as well. So society, just like a human life goes through its own ups, downs and everything in between.
If this theory is correct, millennials will be looked back in history as a strong minded and effective generation just like the greatest generation. We all know the real worst generation of modern times is the baby boomers :
And who better to represent the quintessential baby boomer than Donald Trump himself?
