I very much doubt that any struggling, working-class citizen is going to welcome an invasion that will compete for jobs and housing.
I certainly don't want them in my area. No matter where they are from, or how white they are.
While I was in the Navy, the Soviet Union collapsed. About a year later, my boat got several new recruits who were from former Soviet satellite nations.
Everybody wanted to throw them off the boat. Very many of them were discharged, and sent back home.
Before or since I have never met such lazy, stupid, conniving, paranoid, sniveling people in my entire life!
They were that way due to living under a system that did not reward positive, honorable behavior.
