[Note: this list is for what I believe to be fundamental texts in the area of political philosophy and economics. For my vacation reading suggestions, try https://khow.iheart.com/featured/ross-kaminsky/content/ross-vacation-reading/)
On Amazon, there are multiple editions of each of these books so check for the best price! I also encourage folks to look for used books at abebooks.com.
Oh, before the book list, here's a brilliant and important 1945 paper by Friedrich Hayek that you can read online, though I recommend you print it out so you can really take your time with its 12 pages: "The Use of Knowledge in Society". I believe this paper undercuts the fundamental intellectual underpinnings of the Progressive state.
And for something short and simple, and the piece of writing which I reference more on my show than any other, Bastiat's "That Which is Seen and That Which is Not Seen"
One more thing before the list: A seminal book for my life was, and is, Ayn Rand's novel Atlas Shrugged. It's a book whose reputation precedes it a bit. I think it's an must, but it's long and fairly dense and not what I'd call introductory. It's more political philosophy than economics, though it certainly involves the latter. I encourage you to read it, but for non-fiction discussion of economics and political economy, here's the list...in the order in which I'd probably suggest you read them:
