How to stop the assimilation of American Jews?

I’ve been reading recently about yiddishkeit in the US from the 1880’s to the 1920’s and it made me realize how much we have assimilated since then. I wish American secular Jews still spoke Yiddish and kept closer to our traditions. It’s absolutely heartbreaking to read about Yiddish poetry, theatre, music, and newspapers all while knowing that I will never be able to experience it. I was wondering what solutions you guys have other than everyone moving to Israel, because that’s the only one I can think of; if we don’t all emigrate I feel like we are doomed to assimilate. I’m seriously considering moving to Israel, and I’m planning on going to volunteer at a kibbutz next year for my gap year. I’m very interested and excited to see how that experience will impact my feeling of the “togetherness” of the Jewish people.
