Existing international monetary structures such as the World Bank and the International Monetary Fund have been effective in fostering certain limited national development. However, considering the global situation as a whole, the effectiveness of these structures is restricted. They are dominated by the most powerful nations, as membership is based on each nation investing capital in proportion to its economic solvency. It then participates in proportion to the amount of that capital. Also, the flow of currency is directed to a limited number of specific development objectives within member nations.
Overall images of the global economic system are limited, and even well-informed persons find their reasoning unclear when they confront the question of the system of world distribution of goods and services.
