A High-Five for the Invisible Hand. Choice quote:
"[N]atural scientists have remarkably low standards for reasoned argument when they discuss social science, as compared with the rigor they bring to their home fields."
"So read “The Rational Optimist” for its fascinating history of trade and innovation. But also ponder whether the debate over markets can move forward while it remains a purely religious war. Those willing to confront honestly all the doubts about the “free market” might then actually be persuasive in arguing that it is the worst system humans have ever tried — except for all the others."
