Haha - It's clear where we may differ, but I respect that outlook.
I don't see the world becoming a smaller place as a good thing, just as I don't see a high-speed rail link will suddenly create opportunity for anyone but London.
The world is a varied place, with many different traditions and problems, and I think trying to reconcile integrating that and even more people coming into the country, is just impacting far too many areas and services in our every day lives, certainly what I see from a schooling and health level.
I can't remember what life was like now before I had a mobile phone, less than 20 years ago, but I'm pretty sure I was still able to communicate with people, I maybe just had to work a little harder to communicate!!
Half of life's problems, seemingly, is a lack of self-sufficiency, and I like the idea of seeing this country at least attempt to determine how we go forward, without being told we need someone to always hold our hand.
If my children want to study or live in Germany when they are older, no problem, work for it. Get in line, and accept there will be people ahead of you more deserving, and it might not work out how they hoped.
