The Invisible Wall is a gripping exposé of the part played by multi-national corporations, Third World debt, and trade barriers in fueling poverty and environmental destruction in the world's poorest countries. It argues that, in the post-Cold War era, global rich-poor inequalities will occur on a grander scale than ever before. Noam Chomsky, Susan George and John Kenneth Galbraith are among the critics of GATT's new world order of unfettered market forces.

Avoiding images of human suffering and concentrating instead on its root cause, the program evokes more anger than pity. It exposes the power inherent in food politics, such as that wielded by a single American company which alone controls almost half of the world's cereal production. It looks into a leaked World Bank document which suggests that all toxic waste from industrialized countries should be dumped off the African coast since the local population has no chance of living long enough to catch the resulting diseases. It argues that the new "missionaries" representing the religion of the free market promise future paradise for present suffering, and warns that their trinity of GATT, the International Monetary Fund and the World Bank offers no solution to the real human need of national or regional self-reliance.

"The market system as we know it in the West survived only because there was a mixture of market activities, state activities and state restraint." - John Kenneth Galbraith
