In making his standard argument against “free trade fundamentalism” Robert Wade presents a novel analytic suggestion:

In thinking about these issues, we should also give up talk of “the developing world” in contrast to “the developed world,” and talk instead of a “1:3:2 world” (one billion people live in the rich countries, three billion live in countries where growth rates are faster than those of the rich countries, and two billion live in countries where they are substantially slower).
