To me they're like mere servants of the State, like Lenin talked about in "2. What is to Replace the Smashed State Machine?" in his writing "The State and Revolution"
Under Capitalism, they are its privileged knights that try to deflect and control, if not defend directly its image as "the only option", who have their incentive in doing so, with their class status stake being in their duty to shepherd the means of production and its resulting benefits
However, they don't own the means of production, as they merely manage it for the landholding, industrialist, and financier capitalists
On the other hand, under Socialism, while its privileges will be probably be done away, the PM class on its own would innovated upon, for their new duty of overseeing, managing, and reporting the collectivized cooperatives and state-owned enterprises..
Until the final stage of Communism arrives, I think they're pretty handy
I say this, because I hear such disgusted sentiment in Hexbear against them
The PMC is not a real class as it does not describe the employee relationship to labour and the means of production. The way PMC is talked about online is more like an RPG class in a game than an economic or industrial term. If you have the look of an office worker, if you wear a business shirt, if you don't have calluses, then you are a PMC. Does that sound like a reasonable category to hold?
Here's a good video about it: https://youtu.be/y0KHMHngotM?si=qbUjwXwjsToXQsKx
On second thoughts, I may have to reconsider if there is such thing about a PMC....
