False dichotomy, strawman argument.
You're attempting to suggest that the one and only alternative to the terrible, inefficient NHS is the even more terrible US system.
Lots of countries have much better public healthcare systems, the world's full of them. You've cherry-picked the worst to try and make the NHS look good in comparison.
The NHS is THE BIGGEST EMPLOYER IN EUROPE and THE WORLD'S BIGGEST EMPLOYER OF HIGHLY SKILLED PROFESSIONALS. We're not the biggest country in the world or even Europe, it's a big money-sucking parasite that's bleeding the country dry and making doctors and managers ridiculously rich.
We need to give up talking about the NHS as though it's a religion, or suggesting that the only alternative is the bloody terrible US system, this stupid argument is used as a threat to silence sensible debate. Any decent government needs to start by recognising that it's a mess and needs fundamental reform from the ground upwards.
Gordon Brown privatised substantial parts of it via PFI contracts, so no party has a monopoly on principles. The whole private vs public thing needs open grown-up discussion, not brainless comparisons against the US system.
