How about Mexican radio and television? One thing too that you have to remember is that there was a large ocean between the Germans and their homeland but there is nothing between the Mexicans and theirs. Plus the Mexicans coming over believe half the USA really belongs to them and you'll see how many of them are restoring their Mexican citizinship now that they can be dual citizens. They can vote in both countries' elections now and they can be faithful to their own politicians. Most Germans weren't indigent and illiterate but came with needed job skills and the ability to learn a language, most Mexicans have at best a 3rd grade inferior education from Mexico ---can't read and write their own language much less ours. Comparing Germans with Mexicans is like comparing apples with oranges ---too many differences.
Look, the best thing we can do is end "bilingualism," and of course stop illegal immigration. Do I really have to say that? But the notion that Mexicans are somehow "different" is offensive.
