Adam Smith's central insight remains true today: There is no greater generator of wealth and innovation than a system of free enterprise that unleashes the full potential of individual men and women. That's what led to the Industrial Revolution that began in the factories of Manchester. That is what led to the dawn of the Information Age that arose from the office parks of Silicon Valley. That's why countries like China, India and Brazil are growing so rapidly -- because in fits and starts, they are moving toward market-based principles that the United States and the United Kingdom have always embraced.
