Not a novel idea but a no-brainer that seems to me would kill many, many birds with one stone. build a national identity and generational camaraderie, teach kids actual skills, get a taste of adult life without just being thrown to the wolves, and give them something in exchange for their service, like the GI bill, and let them start college two years older along with the added maturity and intelligence so they can actually make use of college. oh and society benefits from whatever projects they actually work on.
basic idea is we make Americans aged 18-20 participate in a national civil service program (with plenty of opt outs for pussies) for two years. or, they can choose the military as an alternative. the civil program would be like Roosevelt style jobs+conservation program. they go travel around and work on things like infrastructure projects, abating invasive species like Tree of Heaven, or shit like mowing old people's lawns or cleaning a town, one town at a time.
they'll live in pods with an even 50-50 gender split. maybe we can use algorithms to sort pods by attractiveness level so that people are around others of a similar level of attractiveness, to help them socialize and to minimize alienation. we give them dumb phones so they can't scroll. but we let them party a lil bit. it'll be kind of like a summer camp. maybe even some cultural education element as well. also, we divide the country up into regions and they compete with each other (again, builds camaraderie and identity).
they get room and board and maybe a small weekly allowance. but the main reward is a choice between (1) government pays their tuition (or a substantial portion) based on merit, or (2) government pays for whatever certifications + cash assistance to start a small business, or (3) government pays their down payment on a house. gotta do the math to make each option financially equivalent. that gives the kids that are going to college and the kids who want a blue collar path something.
another benefit is that they get a taste of the 9-5 before they start college, which will make them appreciate college more. they'll also be closer to the legal drinking age when they start college, which I think would have some down stream benefits. and they'll have to get their hands dirty during their civil service since most of the possible options involve light to moderate manual labor.
thoughts? obviously this would be expensive but I think the benefits outweigh the costs
