In another generation they will be assimilated, I believe. As I said, the original immigrants gfrom Germany never did learn much English. Their children and grandchildren did. That is why it is important to get the kids learning English and not do the Spanish language classes in schools. Most of the workers my son has on his crew use very little English, but they are trying to learn.
Of course, these guys go home every winter and don't come back until March. They are like the guest workers talked about in this program.
My grandmother came here from Germany when she was in her late 30's, she never spoke a word of German to me. Only English. My father learned English when he came here at the age of 17, never heard more than a word or two of German in my house growing up.
