"But why have they been bewitched by a flawed US system?"
That's one of the most telling points in the discussion. The US health system is largely in private hands, and it's excellent for the wealthy, rotten for the poor. The more that we put our health service into private ownership, the more we're likely to head the same way.
Of course the government insists that the ownership will always be public, and all they're doing is contracting the management of some parts of it to private companies, for the benefit of patients.
The real problem in the NHS (in my opinion) is the heavy and expensive hand of bureaucracy which clogs everything up. The endless box-ticking mentality that's been imposed on them means that lots of people are employed doing things which are nothing to do with patient care, but merely serve the governments' obsession with targets.
