It’s actually a very interesting question of which immigrant groups can transmit culture and / or wealth to the next generations.
Russian-speaking immigrants can transmit wealth but not culture.
German immigrants can’t transmit their culture. I live in a historically German area. Everybody has a German last name. We have exactly zero German restaurants. And zero ethnic Germans supporting our German program. The local Oktoberfest is held by WASPS and features Bud Light and hot dogs.
Italians, on the other hand, are great at transmitting culture. The richest program at my department is Italian, even though we have very scarce interest from students. There’s a bunch of third generation Italians who don’t speak a word of the language but donate money to our program and hassle me endlessly as to what else they can do to spread the love for their culture and language. I have more scholarships and awards in Italian than actual students.
In Spanish, by the way, the only scholarship we have was established by a non-Hispanic American. We have a growing Hispanic community but they have no wealth to share and no interest. Chicano writers in the US are completely Anglo. The way they write, the way they think is as Anglo as it gets.
I’m not saying this by way of criticism. It’s simply the way it is. Russian-speaking immigrants make gigantic efforts to transmit their culture to their children and fail every single time. These are people who almost never assimilate culturally because they are in love with their culture and don’t want to let it go. But the children want nothing to do with it.
