Two Lessons for the Rich: The goal is clear. The goal is a truly human--or at least a more human, more humane--world: a world in which the number of people who live lives that are far too close to those of all of our pre-industrial ancestors is numbered at a hundred million rather than in the billions. In the case of India, we can already see a good way forward along its best development path. And its best development path leads through terrain where computers and telecommunications, fiber-optic cables and microprocessor switches, satellites and packet-switched networks, all make international trade in much of white-collar services (whether reading X-rays, supporting customers, reconciling bills) as cheap and as possible as the iron-hulled ocean-going steamship made trade in staple agricultural and industrial commodities in the late nineteenth century. Brad DeLong is my current economist of choice, probably because he keeps a very good weblog. Well, second to H4x0r Economist Alan Greenspan, of course.
