This, so much. Not the UK, but another western-European country that has slowly succumbed to right-wing rhetoric and fear-mongering. There, legal immigration has continuously been a boon to the economy, but each politician having had to "one-up" the previous one in terms of "tightening immigration" and "looking tough" has only made legal immigration increasingly miserable, and put off skilled/high-earning global workers whose presence was desired.

Of course, nothing has changed for the illegal ones: they haven't (and won't) see the increased burden of legal migration of which they are oblivious. Overall things are only getting worse, and I hate that there's no attempt to having a honest and transparent debate and discourse on the matter.
