Consider the following: if you consider communism to be a bad thing which people should be vigilant against, arguments to the effect that the defining feature of communism is having rail decisions made by employees of a state railway company rather than the boards of Abellio and Arriva[1] probably aren't going to help. Firstly because there's a wee bit more to communism than that, and secondly because the consensus of British rail users is that decision making concerning our railways is currently crap.
There are plenty of decent arguments that Labour's 2019 nationalisation plans wouldn't solve the fundamental problems of those services, but the idea that it's basically Marxist-Leninism isn't one of them.
[1]incidentally entities which are wholly owned by governments, just not the British one
Firstly that involving workers in the ownership and running of a company is a successful model that is working in German for example. Focus on short term shareholder value is not good for employees or the company.
You are posting on a site that has a large percentage of people working in start-ups. Comments like your kind of goes completely against the audience.
Secondary, I've heard McDonnell describe himself as a Marxist. but he is also a politician. Unlike Corbyn he was the one to (incorrectly in my view) seek compromise and common ground with people who were seeking to undermine him. He was the key player in getting Labour to adopt a policy of second referendum, something that an ideological Marxist would certainly not go anywhere near, let alone drive.
There's no actual Marxist I know that would go anywhere near the EU.
Personally I don't believe Marxism to imply state control, or public ownership to mean state ownership.
I'd also see ownership models to include workers and customers. e.g. as a seasonal reference Building and Loan from It's a Wonderful Life.
Of course not everyone sees it that way.
Yes a large portion of readers probably works in startups, the pinnacle of market and financial capitalism and should in all logic despise Corbyn and McDonnell... although that's irrelevant to the discussion.
McDonnell and Corbyn indeed are life long euroseptics and very satisfied with Brexit, which made it even more ridiculous to see so many students cheering them.
And of course there's also the little thing about McDonnell and Corbyn being Marxist and socialist.
Again, too many people still seem not to be willing to see what's not even hidden. History should really be compulsory over the whole of secondary school.
