Milton Friedman and Rose D. Friedman authored a very thought-provoking book. “Free to Choose: A Personal Statement” was published back in 1979.
The tone in the book is very sensibly and realistically. If you are on the fence about being a libertarian this book might just convince you to make the switch.
