Does every other country have a boarder that "allows" millions of people in every year? These EU countries are tightening hard on immigration as they have found that it crushes their social nets. Not to mention keeping defense spending adequate relative to allies.
Immigrants are easily exploitable labor. They aren't sucking up our resources. If anything, we're sucking up their resources.
I live in Texas. Look around me. Who's building these 500,000 dollar homes? Not fatass white people. And who is buying them? Not the people building them.
Several million people migrate to EU countries from outside the EU every year, yes. The number will be lower than a million for most individual EU countries, but then the individual countries also have smaller populations than the US.
If this was so easy, what is the plan?
