Hi there, I am not really into reddit and that subreddit and would like to get your points about it. It seems there are people who see themselves as leftists and are at most vulgar marxists in the majority.
The last post I saw was about saying people who want to use real existing power structures to get Nazis fired are actually perpetuating the power of bosses and as such you have to build dual power instead of getting Nazis and Sexists fired. It ended with "which side are you on?".
I like the formular: "The wage labourer is doubly free (free to chose where to work - as opposed to serfs or slaves - and on the other hand free of capital from which to draw profits or land to draw rents from which enable them to subsist from) as such he is forced to work to subsist". This means that CEO's who have 20 years to life are not in any meaningful sense working class, when they have $16k * 20 in savings.
This is different from Marx conception of capital, but I think it is an easy to understand upper boundary. Naturally the social relations are what actually matters. Those you already outlined in your post.
