Most of the Polish people I know who lived abroad and have moved back to Poland have brought skills, often highly educated children, relatively large amounts of money, and what I would describe as an international forward thinking attitude (i.e. they aren't voting for PiS).

Its not inevitable that a lot of young people from the UK moving abroad is a bad thing for the UK, as eventually a bunch of them are going to come back.

That said all the flag waving bullshit I see the UK doing does put me off returning.
