Their concentra tion, then, is on restricting the number of future births. The standard call of the ZPGers was for a compulsory limit of two babies per woman, after which there would be government-forced sterilization or abortion for the offending female. While the population controllers seem to have given up for advanced countries, they are still big on population control for the Third World. It's true that if you look at these countries, you see a lot of people starving and in bad economic shape. But it is an elementary fallacy to attribute this correlation to numbers of the population as cause.
Population rises when the demand for labor, and living standards rise, and vice versa.
A rising population is generally a sign of, and goes along with, prosperity and economic development. England, Holland, and Western Europe generally have a very dense population, and yet enjoy a high living standard. Africa, on the other hand, most people fail to realize, is very thinly populated. And no wonder, since its level of capital investment is so low it will not support the existence of many people. Critics point to Rwanda and Burundi as being densely populated, but the point is they are the exceptions in Africa.
