The Weaver Reads reviewed The Communist Manifesto by Karl Marx
Goodreads Review of the Communist Manifesto
4 stars
I'm not sure about Marx and Engels's solutions, but the first section of the Manifesto--diagnosing the problems of capitalism--feel like they could have been written today. Dependency theory and Accelerationism almost seem to be built into the Communist Manifesto: capitalism will spread throughout the world, tying even the least developed regions to its core; capitalism will create the weapons that lead to its collapse; and all of that.
It's worth revisiting from time to time. It's short enough, so it doesn't take much effort, either.
