Hope you have that attitude in 5 years or so when you need one of these said social services. Unfortunately you will not have a NHS or benefits. The native population looses out for someones sense of moral high ground. If you are happy to give up your place for some migrant that's great but don't expect me too.
I don't understand how when these services are struggling already another mass influx is going to help them? I don't get this progressive thinking it fly's in the face of common sense?
As I have said several times already, I've heard the same thing since I moved to this country in the early 70's.
BTW, most social services wouldn't be running today without the access to cheap immigrant labour that it has today. So when you next pop down to your local hospital think about that.
