Okay, your challenge is to have, by any POD you want, a USA where individual cultures are retained: German is still spoken, so many more German-Americans retain their culture, same with Poles, Italians, the Dutch, Slavs and anyone else. Essentially, a USA where multiculturalism is the norm but not he „melting pot“ kind, a multiculturalism that recognizes the differences of each individual culture and promotes them.
