Among the many factors that have promoted economic change, I believe that technology or, rather, change in technology is the most prominent. I realize that it is dangerous to look for 'ultimate causes' in a world where everything seems to depend on everything else. But I believe that for the most part the economy, and ultimately the society, must adapt to the conditions that technology creates. If it cannot adjust to the challenges of changing technology, it fails.
