Here is the problem with his augment the US does not have the infrastructure to allow invaders into the country. Yes, I said invaders because if you are not willing to assimilate then you cause social problems. That is the reason we have an immigration process.
"assimilate" That's funny, the immigrants I see around town "assimilate" just fine. Jobs, family, improving their homes, going to church. Or was "whiten up" what you were looking for?
How about learning the language. The US is not as bad, but you have countries like England that have issues with honor killings and rapes, and they treat foreigners better than their own citizens.
Despite Trump's protestations and Holy Proclamations, the United States does not have an official language, befitting our history as a nation of immigrants. How about soft Americans who demand "everyone has to speak like me!" learn multiple languages, like practically everyone else on the planet?
Yet all of our street signs and official documents are written in English even though most of our ancestors did not come from England. I is fine to learn the thousands of languages in the world but people should know English if they are going to make to US home.
