People in developing countries are hungry because they are poor, not because there is insufficient food or land available there. Even when people are starving to death, there may be quite enough food within the country but they cannot afford to purchase what is available.
One of the major contradictions in the international economy is the fact that productive resources lie idle in developed-market economy countries because the largest group of potential customers, namely the developing countries, lack the means to purchase the output, even to the extent of satisfying basic human needs.
