Could you blame us though? After years of "you'll understand when you're older and get more conservative" it starts to feel a little patronizing. I think there's some serious age-ism going on in the US and it isn't primarily pointed at older people. Younger people are almost entirely unrepresented in government and our interests are not being seen to. I'm not saying it's because they're old and their brains have shriveled or whatever, but their material conditions do not align them with young peoples' interests in a lot of cases.
Climate change and social program apathy are forms of ageism as far as I'm concerned. Where's that student debt bail out? I'm going to have negative wealth for some time, just because I decided to get an education and be a more effective worker.
Counterpoint, Parenti is still alive and not cringe.
