I may be misunderstanding you Chickened but UK certainly does not run Canada. Canada is a soveriegn nation with her own parliament and rightly proud of her independence. neither would i agree that Canada's economy is dependent on her neighbours.
I don't understand your reference to WW2 or it's relevance to healthcare. I don't believe that people any where in the world, and we all know that we are going through tough economic times, chooses to be poor. The poverty that I have seen in US has been around some of the richest areas, for example Miami and Los Angeles. They might be glamourous areas but go outside the towns and you will find whole communities living on the edge of society. I have spoken to people who told me that if they didn't catch fish, they wouldn't eat that day. They also had to suffer the indignity of being chased away from richer areas, like lepers.
Travelling across the mid west, I have seen some of the poorest and most isolated settlements, even barefoot children. What life chances do these youngsters have? Their educational opportunities are limited by geography, and their lives defined by the poverty that has enslaved their parents and probably grandparents. It is disingenuous to say I should look at the poverty in central America. That is like saying 'I'm fat but he's fatter!'
The healthcare system in UK is not of course perfect. There is always room for improvement, and many countries around the world have different models of a National Health Service which provide their citizens with excellent services.
Your bank manager from South Wales perhaps didn't tell you that it is one of the most deprived areas of UK. It has a national assembly, with a budget, and they choose to spend money on free prescriptions for everybody in Wales. People however, in England, do not get free prescriptions, but guess what; nobody riots in the streets because they are paying for a service that is free in Wales. If you want to understand why, I will tell you. Wales is geographically remote. It's old industries of coal mining and engineering has gone, along with the skill base that supported it. It has found it hard to encourage investment by new technology businesses, despite many regeneration schemes. Could all the people of South Wales leave and come to US, or get jobs in the City of London? Of course not! Do they deserve a break? Of course they do!
