Have you read The Road To Serfdom by Hayek? Anyone trying to convince me free markets aren't the best would have to make a compelling argument how Hayek is wrong. Because all I have ever seen is more central planning, more restrictions and more interventions and the outcome has been exactly as predicted by Hayek. Particularly hard resonates the point that people stop trying to improve their own lives by working and improving their skills and instead people become increasingly political.
