If you’re unwilling/unable to read books, the creator of Lemmy will read some to you, as will Socialism for All, often with his own commentary. Here’s a bunch of Michael Parenti’s speeches, if you don’t want to read his books.
David Harvey is a good-enough Marx explainer that Prole Wiki quotes him, though I don’t know if he is ML himself. His YouTube channel is Politics In Motion.
BadEmpanada is a bit of a mixed bag, but has some good, well-researched stuff for beginners. But sometimes he’s just an asshole. Midwestern Marx also has some good stuff for beginners, but he’s a problematic revisionist with his imperial core patriotic socialist tendencies.
The Deprogram is relatively basic stuff. They now also have a thrice-weekly news channel, First Thought, and each of them has his own channel: Second Thought, Hakim, YUGOPNIK.
I’ve never heard JohntheDuncan say anything I disagreed with, so I assume he’s ML. I just really like the guy and his work.
Geopolitical Economy Report and Michael Hudson are not ML, but they produce good stuff.
Here are some others I’m aware of, but haven’t watched enough to recommend nor vetted to be ML. I’m curious what others think of them.
