So the UK was a socialist country after WWII, was it? Riiiiight.
The NHS grew out of a 1943 report written by a Liberal under a Conservative PM. The only major change that Labour made was a fully national organisation instead of a series of regional organisations - but that's in line with Labour's nationalisation ethos. That Labour then claimed the NHS as its own is one of the biggest continuing conceits of post-War UK politics.
There was clear consensus across all parties that a national health service of some description was both desirable and necessary.
Quite how rationing is socialism is beyond me. It was a necessity implemented by a government within a democratic framework. We didn't have a surplus, so things were divvied up accordingly. It's not as if the countryside was turned into one big kolkhoz; the farmers supplying the nation generally owned and worked their own land and were paid for produce, not penalised for not hitting unrealistic targets.
You may as well say that the government has taken on socialist principles over the last year. The flippant might say that keeping everyone under virtual house arrest is hardly a desirable action but, moving quickly on, the government imposing collective measures in response to, or to avert, a development isn't automatically socialism. It's just government.
The Great Reset is just academic sleeve-pulling. In the real world, it has as much economic foundation as Corbyn's Million Homes for the Homeless; in other words, it's groundless - a nice idea(l) but unachievable and, ultimately, unfair. It's more 'one potato each' nonsense peddled by comfortable middle-class polemics who if one potato each became their own reality would be squealing like stuck pigs.
