The thing is, youth liberation cannot be achieved without the end of capitalism and the liberation of workers. We cannot expect to gain our human and civil rights by working with the bourgeois system, because the bourgeoisie relies on the dehumanization and subjugation of youth to have the workers feel like they still have some kind of property. Your rights under capitalism are directly tied to your ability to produce capital. Since children cannot produce capital, and teenagers are not guaranteed the fruits of their labor, they are subjugated by the adult bourgeoisie. Hell, even CPS exists to pacify the youth (feeling like there’s a way out of abusive situations) and adults because CPS protects their “rights” to abuse kids. Calling for expansion of CPS is capitulation and will inevitably be weaponized against parents who treat their kids with respect. The best solution is securing the right for youth to leave of their own free will and have a place to go, which can’t happen as long as housing is commodified under capitalism.
If we are to fight for youth liberation, mere protests and petitions and (anarchistic) individual action will not do anything because the current system hinges on the oppression of children and workers. The solution is to ally the revolutionary struggle for the working class and the struggle for children’s rights. It is no coincidence that socialist countries like the Soviet Union and the DDR advocated for the protection of children from violence and recognition as people, or that their education systems were largely more democratic. Youth alone are not a big enough sector of the masses to make a real change, and real change cannot exist within the current system, so the best course of action in terms of youth liberation is to align with the revolutionary movement.
In Marx’s time, women’s liberation was unheard of, and yet he championed it as a goal of socialism. The DDR decriminalized homosexuality 20 years before West Germany did. Now that youth rights are the new frontier, there is little doubt in my mind it will be the (revolutionary) socialists who lead the way.
