No, that's true, I don't see any other way it could work. I just get frustrated at the relentless concentration on immigration, overwhelming every other economic policy.
And, really, I'm not prepared to deal with UKIP or other anti-immigration positions as being reasonable ones - they're specifically aggressive towards me, my family and a lot of my friends. I find it a challenge to treat people subscribing to them as worth listening to. I can understand how they come to those positions but they are basically telling me and mine to fuck off.
