WE suffer from a congerie of attitudes that cause us to be surprised by the idea that technology might be beneficial—and perhaps by the underlying principle that free markets are fundamental to our civilisation. A part of that congerie is the eclipse into which the idea of markets passed for a considerable part of this century. It was assumed by Left and Right alike, and indeed is still too often assumed, that markets do not work properly and that governments have to step in. I'm not talking about communism here but about all-pervasive regulation and control.
