" I managed to come up with enough $ for a private doctor who immediately diagnosed the problem (type A flu which had now caused pneumonia in both lungs) and prescribed the medicine she needed (a misting machine with a medicine to open her lungs plus a powerful antibiotic)."
I'm glad your wife recovered but I would take issue with part of the statement you made.
Did this private doctor tell you that type A flu is a virus, on which antibiotics have no effect and the result of this unnecessary prescription is that many resistant strains are being created.
Actually, the Brits I have heard from seem to like their NHS quite a bit and would never exchange it for American "healthcare" (nor the Canadians).
