I have PERSONAL experience using the British National Health system. It is NOT all that good. I have posted some of our own "horror" stories in this forum in the past. Rent the movie "Calender Girls" for a bit of insight. They don't even have waiting rooms with chairs in many hospitals over there. They STILL have MANY hospitals with LARGE multibed wards. Not the best for controlling cross infections.
The taxes are "Killers" and while lower than when I lived there they still insure "Enforced Laziness". I just does NOT pay to work hard there. The Government takes way too much if you do.
Lastly, the Brits, as most of Europe, has NO concept of real freedom. They are USED to being ruled. They have been ruled for several thosand years and the idea that they can control ANYTHING in their is strange to them. Most there would prefere to be told what to do for health care.
Do NOT fall for ANY stories about how good it works over there. It is NOT all it is cracked up to be.
