Who is a PMC lib, who is working class? It's obviously not office/factory anymore, most people don't work in factories, right? Why was the focus in communist thought on factories and not, servants, drivers, nannies, maids, cooks and secretaries of the rich – they seem to be easy to radicalise because they see the shittiness and incompetence of the rich day to day, and more importantly are most needing of a union because of the likelihood of abuse by their bosses.
Was it because they don't exactly work together? Can't exactly chat and radicalise? Hard to strike? How do we bring gig economy workers together when the same barriers apply to radicalise them?
For me it helps to think of these class labels as roles rather than identities, which runs somewhat counter to common political discourse on class in the US. This could mean some people occupy multiple roles, or it could mean that some occupy a specific class role, while personally identifying with another class.
