Probably a product more of age than of generational specificity.
You get used to your comforts, you probably have investments, you’re consumed by trying to get ahead enough so that you don’t have to die at your job, just in a nursing home what takes all of your money.
Gen X myself, and maybe an outlier, but I’ve probably become more radical as I’ve aged rather than the other way around. I’ve been stuck being poor for decades before finally “making it”, and that has really driven home the awareness of how fragile it all is. That, and just general omnivorous reading that includes a lot of depressing scientific literature regarding climate change. It’s terrifying.
I vote for the left (I would have happily voted for Sanders), support local measures and politicians that lean towards social policy and move towards things like green power, etc.
So yeah…not necessarily a thing you can just pin on a generation, though each generation will have some stronger proclivities than others in certain areas. The millennials will have to watch out, they’re next to fall for circling the wagons to protect whatever they might have, hate on their gen’s billion- or trillionaires.
