David,
There is not, and never has been, any reason for the UK government to treat immigrants from the rest of the world differently from EU immigrants.

Yes there is. EU migrants can not be refused, so all control has to fall on non-EU people.

Bwm, there are rich and poor on both sides, but big business want Remain to keep their gravy train running.
If you could argue your case you would not have to resort to name calling.
