That surprises me somewhat. It strikes me that if I were a 20 year old neutral attempting to decide which nation to choose as a home - at first sight, the UK would lose hands down.
I know that healthcare issues can destroy people's finances here but that has to be balanced off against the fact that, for one vital area, the poorest of Americans apparently have much better cancer survival rates here than does the average NHS user back home!
Once you delve below that surface however, it may well be far more complex than I could possibly see in a snapshot tour but there are just so many things here in abundance which we no longer have: decency, duty, politeness, care, cleanliness and service to name but five - such matters certainly influence your thinking.
What truly amazes though is that so many of the things which have helped to drag down our society began HERE. It is all most puzzling.
Do Americans come up with stupid ideas and then prove to have a greater immunity to their effects than we do? - It seems a possible explanation.
