There has always been high immigration in the US, its a country built on immigration!! Like others have said, the current levels are not higher then in the past, its just the political parties that are using it to hide the real problems of ultra rich and corporations abusing the country. In regards to changing society; what is changing? The language? Again, the US is built on immigrants. Are the Italian - Americans in NY going to stop being Italian - Americans all of a sudden? No, they will continue being who they are; maybe they will pick up another language or some new recipes for their cookbooks.
