My uncle asked me for a primer on socialism. I was thinking maybe Socialism Made Easy or Socialism: Utopian and Scientific. Anything that might be better?
For context my whole family are through and through vote blue liberals. It's sad to say but most of them didn't even like/vote for Bernie during the primary cycles. They aren't really hardcore anticommunists though and have always been good on unions and labor generally, moreso the problem is really anti-Trump/pro-Dem brainworms. Maybe there's something more modern to share that I don't know of.
On socialism as a realistic, achievable system with a modern perspective I have to recommend Towards a New Socialism. Caveat being that Paul Cockshott is a TERF POS.
For an introductory text to get started just tell him to check out the Communist Manifesto, easy to understand and light on the jargon.
Honestly I’d almost recommend Principles of Communism over the Manifesto for this purpose. I found it much more digestible.
I've read TANS and thought it was really nice and digestible too. I've been in the process of working through How the World Works for a couple years now as well, it's great for when I have the time to focus on something a little more academic. Too bad Cockshott is such a reactionary shithead.
