Maybe it's just the company I keep, but I see a lot more sacrifice when it comes to community organizing, GOTV efforts (beyond just posting some doodad on FB), canvassing, and more importantly supporting others running for office who are NOT the traditional middle aged middlin' to wealthy white penis-haver from the "Millenial" generation than I do from the people my age and older who sit around on their asses bitching about them.
I think a lot of people forget about all the voter suppression methods that have been part of many states for years and years, that make it extremely hard for college students and frequent movers to get their ballots or make it on to lists, ect. To say nothing of the idiotic campaign of voter suppression that is the avalanche of "everyone's the same, why bother voting" that's vomited everywhere. Hmmm. Wonder who that targets by and large.
When I show up for community meetings, millenials and younger gen-xers make up the majority of people there, not silver haired white guys. When I've needed to recruit people to walk with me and go to events to do voter registration or chase ballots during election times (help find people whose signatures were rejected, so they know they've been disenfranchised and help them rectify it) they've been millenials who are actually giving up a lot of after work or lunch break time, not the old people with lots of time to spare and senority. The running for office trainings we've been putting on are swamped with those under 35, women, and brown or black people.
I get that a lot of people can't do much but nag their friends and coworkers, but please don't shit on a generation that is probably a lot more involved locally than yours.
ETA: I'm almost 45, so not a millenial. Just getting kind of tired of people dumping on them. I paid about $30k for my bachelors degree, could set my pay level (outside of government employment) and get it because the job market of the 90s was so awesome, know a ton of people my age who became independently wealthy because of the dot com era (those that didn't fritter it away and invested wisely, that is), I could buy individual health insurance for $90 a month, schools maybe weren't funded as well as they could have been, but they weren't at the level of falling apart even in the rich suburbs level that they are now for K-12. Pretty sure the people under 30 are getting a shitty ass deal than the one I got. So I don't know, if they feel some futility about things, or decide not to work themselves to death for less than half real-worth wise hourly wages than what I got at their ages, I really can't say I blame them too much.
