A question I've been mulling, I'm curious about how different cultures hold on to their distinctive cultural traits through generations in the US. I know an awful lot of first generation Chinese- and Indian-American kids who have intense battles with their parents over the filial piety issue, but it seems to almost universally disappear by the next generation. Most third generation Hispanic immigrants don't even speak Spanish. Are some cultural traits more enduring?
You see multi-generation Islamic kids in Europe that really don't share European values, but is that a ghettoization effect or something intrinsic to the culture? The Somali community in the US seems to have some trouble, largest number of ISIS supporters and such.
I wonder if anyone has looked into that kind of question in an accessible way. Thorny subject.
