Socialism and the working class have been a thing in England for a very long time. All the way up until PM Thatcher and the unions. Even now, today's Labor party is quite an example of modern Socialism. The problem with Socialism is that is almost always turns to Communism and then to something along the lines of Totalitarianism. See China for an easy example.
That and running out of other people's money.
Sorry mate. That's just completely untrue. It seems to be a pervadingly American view on Socialism straight out of the McCarthy playbook.
There are a significant number of societies in Europe which operate along Democratic Socialist/Socialist principles. They're a long way from Communist.
We've had Labour Governments in the UK. But never come remotely close to Communism. Socialism is reasonably prevalent in the UK (where even the Conservative Right Wing retains some Socialist Policies and Institutions). Communism is very unpopular. Of course, what the Right Wing here try to do is conflagrate the two because, a) it scares people, and b) it wins Elections.
Don't be a scaredy cat. Socialism isn't a dirty word. Ask Scandinavians and anyone who's benefited from major NHS treatment here that hasn't cost them bankruptcy.
