When people ask me where I am from, and I say "California", the response is 9 out of 10 times, "mate, why would you want to be in Nottingham?". They can't believe that I would choose to live here! This got me to thinking, and here are my thoughts, would love yours:
There seems to be a lot of people disillusioned with the UK, and I'm talking about native born Brits here. I suspect that if there were a free movement of people agreements between the UK and the other major English speaking countries, there would be quite an exodus of people under 50 years of age from the UK.
The fact that there are already are a lot of Brits living in Spain or elsewhere in the EU is not really relevant here. I think because, most Brits, would much easily decide to move to the US, Canada, NZ, or Australia.
When it comes down to it, what is the point of having such strict restrictions on labor between the US(and other English speaking countries). Is it only to have tighter controls on terrorist suspects? I think there would be a way to handle that even with free movement of people. If two countries are fairly developed, why have the restrictions?
Anyway, that is my theory anyway. What's yours?
