Depressing as it is, it's fairly typical for people to skew rightward as they get older. The problem is if Gen Z is already starting at a certain position, right now...where will they be at when they reach the age of today's boomers or Gen X/Y?
Remember: the boomers brought us the 60s. Over the years, the narrative has morphed from the boomers' parents (and reactionaries among the boomers) clucking their tongues about the 60s to: OMG, the boomers are all in for donvict, and "okay boomer" and so on. Boomer is now shorthand for Faux News and hate radio addict. Not so long ago, that target demo was the boomers' parents.
So, if it can happen to them, it is likely to happen for Gen Z, but maybe even worse.
The boomers were actually better than Gen X. The only reason we think people get more conservative is because we had a generation with reliable news. Then as they got older they kept Fox News on whenever they weren't watching something else, just all the time. They didn't realize Fox was propaganda and Gen X hasn't realized CNN was bought out years ago with the specific idea of turning it into Fox News 2.
What we need in this country is some media literacy.
