I don't believe there isn't a serious disease not dealt with in the UK? I have no information on Canada.
One thing, whatever you think of it, philosophically (for a lot of it not much in my case), Cuba has an amazing healthcare system. In that it provides for everyone, is at the head of new medicines, and great technologies like biotechnology. They actually pay for a lot of it through trips to other countries to provide high quality healthcare - the countries, in return, to economic or political favours to Cuba.
You think businesses should own healthcare?
I believe in a non-state LHS.
I've seen photos of Cuban hospitals (outside the major cities). All rat infested. American hospitals gleam their so clean. Despite this, Cubans and Americans have the same life expectancy. Should tell you something.
