I'm afraid you've got me all wrong.
I'm actually pro immigration, my father is an immigrant.
What I'm against is uncontrolled low skilled mass immigration, which forces us to impose a discriminatory immigration policy against people from outside the EU.
The current system favours mostly people classed as white europeans.
Surely an immigration system that treats everyone the same no matter where you were born is fairer?
Every other country in the world that has full control of their borders are not racist are they?
Maybe it's actually the remainers who wanted to keep the current system that are racist
Regarding wages, of course they will not shoot up straight away, but if we are able to control the supply of low skilled workers entering then businesses will gradually have a shorter supply of cheap labour.
Gradually wages would rise for low skilled workers and then hopefully governments can stop subsidising businesses with tax credits and the like.
