Age here is a proxy for wealth, of course.
I don't think that because Boomers and (a lot of ?)GenX tended to grow more conservative as they got older proves it's 'the natural order'.. Millennials are approaching 40 now and the liberal ones I know are still very liberal..
I'd argue that Truman getting elected in 1948 meant that there were a lot 'progressive' older folks back then. Especially since there was a more conservative "Dixiecrat" on the ballot as well.
So growing old and becoming conservative may not necessarily go hand in hand...
I've also read it cyclic, with the pendulum swinging from very conservative to very liberal every couple of generations ?
And if, hypothetically, a generation were to grow up and find themselves unable to afford a home of their own, unable to afford a family, and unable to land a career, they will find themselves with very little to lose and very little incentive to preserve the status quo, regardless of their age.
To give some more solid data than people in my circle of friends: https://en.wikipedia.org/wiki/1984_United_States_presidentia... This is the demographics for the 1984 election, the one where Reagan wiped Mondale out. Among 18-24 year voters, 39% voted for Mondale (liberal/D); 61% voted for Reagan (conservative/R).
Now, let’s fast forward to 2004, which is the first election where young people were more liberal than older generations: https://en.wikipedia.org/wiki/2004_United_States_presidentia... Here, among 19-29 year old voters, it was 54% Kerry (D), 45% Bush (R). It was also the last election where a Republican won the national popular vote.
This year, with 18-24 year old voters, it was 65% Biden, 31% Trump: https://en.wikipedia.org/wiki/2020_United_States_presidentia...
Point being, our youth and our society are a good deal more liberal than they were 15 or 25 years ago.
And the generational thing is what I brought up originally. Boomers and some GenX don't necessarily 'point the way' that every generation will age.
My hypothesis is that when they are young and underdeveloped, they have incomplete understanding of the world, are prone to believing in unrealistic utopian ideas, and hence are easy to manipulate. No wonder, the leftists want the voting age to be lowered even further.
As they grow older and wiser, they see it for what it is.
The younger conservatives are explained by the fact that some kids who grow up in conservative households don't fall for the same manipulation and older liberals are explained by the fact that some people are more reluctant to change, mostly because they weave their personalities around their identities in early adulthood. Some is of course explained by influence of peers (i.e. people adopt a political view to fit in) and hence location... but I think this covers it all.
I know I will get downvoted for this which is fine but I'd like to know your hypothesis for the same population leaning conservative as they age is... if it's not too much trouble.
Please compare https://en.wikipedia.org/wiki/1984_United_States_presidentia... and https://en.wikipedia.org/wiki/2004_United_States_presidentia...
Observe: The 1984 youth voted conservative. The 2004 youth voted liberal. And, oh, the 2020 youth voted even more liberal: https://en.wikipedia.org/wiki/2020_United_States_presidentia...
