This is exactly the flawed reasoning I am criticizing. Of course, if you "cut off the labor", they wouldn't come. But experience has shown, that this is impossible. Especially not since a large proportion of the US economy absolutely depends on these workers. And a large part of the $18 billion dollars every year is spent on trying to police immigrant laborers. And no, wages will not rise, because wide-scale disruptions would lead to the worst recession since the 1930s. But that's hard to speculate because, to reiterate, "cutting off" the labor in any reasonable timescale is completely infeasible.

What I envision for the future is stopping immigration controls in the entire developed world. Preferably happening all at once. The burden for Germany would likely even decrease. Because just as it is, Germany has been selected for the first breaking point, and the situation is such that pretty much anybody can immigrate to Germany already and not be deported anyway...
