It is playing out that way
all our waves of immigrants since the 1870s, LEGAL immigrants had to prove they wouldn’t be a burden on our gov’t.
That is still the requirement in any country in the world to which anyone would immigrate.
Is there any other country that gives some benefits to people who break the law by sneaking in?
Forget about the illegal aliens who get benefits, usually thru their US born children. There are far more LEGAL IMMIGRANTS who are getting more benefits. We are importing poverty. Milton Friedman said, "You can't have free immigration simultaneously with the welfare state." We have both.
