The problems of the world are all down to rapacious corporations and faceless international bureaucrats. Sending the WTO packing was a blow for mankind. So it may have been, but not for the reasons expressed by some of the WTO's most vociferous critics. The question should not be about whether trade is good or bad, because self-sufficiency is no more an option for countries than it is for individuals. Most of us do better by concentrating our efforts on the things we are good at, and using the proceeds to buy toys for our children, and hire plumbers to put in our central heating, than we would by trying to do everything ourselves.
Trade is normal and natural.
Suggesting otherwise leads down the blind alley of trying to argue that countries would be better off behind protective walls. North Korea's example tends to suggest that they are not. Nor is the idea of a WTO itself a bad idea. Having a system based on rules is better than one in which the big countries can frighten and bully small countries into submission. Robert Maxwell used the British libel laws in precisely this way to keep his malfeasances out of the public eye.
