It’s from Paul Samulson, an economist I don’t really like. He wrote many things during the cold war that explained how the Soviet Union was more efficient than the US. All of his stuff was proven to be wrong when the USSR collapsed. His and Hayek’s works were diametrically opposed to one another. Samualson championed central planning and a command economy whereas Hayek spoke at great length about the strength of emergent orders and unplanned economies (guess which one I like:-) One had to be wrong, turns out it was Samualson… Anyway, his great quote was
“The problem with free competition and capitalism, like the problem with Christianity, is that it has never been tried.”
