There are quite a lot of people who think something needs to change. They will have different takes on the problem and the solution. Furthermore, most people are able to hold more than a single thought at the same time.
I think that both legal and illegal immigration are currently way too high, and that it is urgent to address this.
I'd like legal migration back to '90s levels (eg < 200k immigrants total/ 100k net), with a big emphasis on skilled migration (useful skills, not excuses like 'blogger' - which is currently on the skilled mugration list). And far more attention paid to integration - both in giving visas initially and on approving the progression through ILR and citizenship.
And I'd like illegal immigration down to Denmark levels. Which is under 1000. And only the ones who are approved staying after initial decision - no costly appeals which take years.
