Fair to add that, despite every winning party promising reduced immigration on some level, and everyone that wanted to remain in the EU rightfully annoyed that Brexiters were simply voting because of migration, nobody in power has ever given the people what they want in this regard.

And no one will, because the UK wants cheap foreign labour. To no one's surprise, immigration rocketed after Brexit.

This allows the ruling party - the one whose names and faces keep changing, but whose policies don't - to keep using immigration for political leverage while also benefiting from it.

> nobody in power has ever given the people what they want in this regard

Net migration in the UK dropped by 400,000/yr in the last year and they’ve toughened the criteria further so seems unlikely it won’t drop further.

It doesn't really matter, people's grievances won't go away because those have nothing to do with immigrants anyway. They will just move on to the next scapegoat.
