I’m not a fan of economists in general but a couple like Friedman were some of the greatest minds in our history.
Agree with him or not, Friedman is compelling with his arguments and logic.
Think about what he says and try to come up with a logical (and not emotional) rebuttal. Its actually not easy.
What this does for me, and I’m no unvarnished capitalist, is demonstrate how the real world functions (and not how I would like it to function!)
