Want to give these libs some theory to read but think they'll be scared off by Marx and Lenin? Anything a bit more SocDem friendly that gets the basic points across - class consciousness, why they need to organise and how etc.?
Shoer articles preferred but anything will do tbh
Not exactly short, but I like Blood in My Eye by George Jackson and I think there are audio readings of it out there as well as text. I feel like it's a good one for jumping straight past the risk of "working class, but western chauvinist" phase right into the experiences and thought process of a black revolutionary who put in a lot of theory and practice work while being an imprisoned enemy of the state, and in the context of the US. Making it more concretized and direct for a USian than, say, State and Revolution, which is also an eye-opening one in its own way, but could be read abstractly as "the working class needs to seize power" without any regard for the unique conditions as they relate to the US.
Anti-Nixon rocket launchers! (thanks to the Marx Madness reading of this book, I will forever have the image of Nixon's face on a rocket doing a Futurama style "AROOOO" right before it explodes in my head every time I think of that book)
