A more full account from Paul Krugman on some of the topics I originally brought up yesterday.
Still, can innovation and progress really hurt large numbers of workers, maybe even workers in general? I often encounter assertions that this can’t happen. But the truth is that it can, and serious economists have been aware of this possibility for almost two centuries. The early-19th-century economist David Ricardo is best known for the theory of comparative advantage, which makes the case for free trade; but the same 1817 book in which he presented that theory also included a chapter on how the new, capital-intensive technologies of the Industrial Revolution could actually make workers worse off, at least for a while — which modern scholarship suggests may indeed have happened for several decades.
What about robber barons? We don’t talk much about monopoly power these days; antitrust enforcement largely collapsed during the Reagan years and has never really recovered. Yet Barry Lynn and Phillip Longman of the New America Foundation argue, persuasively in my view, that increasing business concentration could be an important factor in stagnating demand for labor, as corporations use their growing monopoly power to raise prices without passing the gains on to their employees.
