The premis of the OP is very dramatic but nothing like the truth as far as the U.K. is concerned.
Socialism in government came about at the end of WW2 in Great Britain.
There was a general election and one group of politicians said lets have some decent quality of life(Like UHC for eample) for those in the population who ARE’NT members of the hereditary upper class or the rich…
And being a democracy the majority, who surprisingly enough were none of the above, voted those politicians into government.
There were no riots,arson attacks,assasinations of prominent figures or of the rich or the nobility.
There were no threats of revolution, tacit or otherwise.
No appeals to the Soviet Union for armed intervention,just one person,one vote.
Boring isn’t it?
And when you look around the U.K. today there seems to be a surprising number of nobility un guillotined,ditto Royalty,in fact not only is the Queen still in possession of her head but she’s the Head of State.
Ah what about Rich people though?
Amazingly they haven’t all fled abroad after being stripped of all their money and possessions, we not only appear to have rather a large amount of them but we have foreign Billionaires and Millionaires queing up to live in our country .
Yet we still have UHC and a welfare state and we are still one of the most powerful Capitalist centers in the world.
I can understand wealthy Americans not wanting UHC for example .
But the mind set of those who aren’t very well off at all,not even compared with me!who are so vehemently against UHC is an impenetrable mystery to me.
In the old days we had forehead knuckling serfs who though they had nothing would fight to the death to preserve their Lords power and lifestyle.
Maybe its the same mindset of Americans with very average incomes who are so dead set against anyone trying to improve their quality of life.
I really dont know …
After all who needs" Heavys" to keep the the exploited down when they’ll do the job to themselves and thank you while they’re doing it.
Before anyone wonders I am totally against Communism/Marxism and totally for Capitalism ,but not to the point of masochism.
