Nobody at all is suggesting introducing a US style healthcare system in the U.K. I’m no supporter of the Conservative party, so I am reluctant to defend them, but that is not and has never been their policy
Of course it’s not their official policy, but there are several senior Tories on record saying that the NHS should be privatised.
Regardless, there is no proper discussion about how healthcare should be organised, so the US style system is exactly that toward which the country is sleepwalking.
Over the last 10 years the NHS in England has been fragmented. Bits of it have been sold off and some of the less desirable bits of it have been stuck back together by Dr Frankenstein. It has also been starved of funding for staff and infrastructure. Waiting times have soared and rationing has been introduced. And the Tories are lying about extra staff and new buildings.
All of this will lead to more people taking out more and more private health insurance, which will enable the Tories to continue to wind down the NHS because their voters and members are unaffected.
And there we’ll be: a two tier American style system, without any need to make any unpopular manifesto statements. Unless people wake up now.
