How does that deal with the (2/3rds) majority of migrants to the UK - i.e. non EU nationals? A majority of EU nationals travelling to the UK already have a job in any case. Sounds like more wind and pi$$ to me and won't deal with those sneaking in.
What if all the British social scroungers are transported into let's say Romania for example. The cost of living and housing would be cheaper. Romania would befit as they will be spending their dole money into their economy.
Also would be cheaper to jail all our convicts abroad as well.
