2. Population growth in Rwanda, in Sudan, in El Salvador, in the slums of Lagos, in the highland hamlets of Chile, can devastate those places. Growing too fast may mean that they run short of cropland to feed themselves, of firewood to cook their food, of school desks and hospital beds. But population growth in those places doesn't devastate the planet. In contrast, those in the developed world easily absorb the modest annual increases in our population. These countries seems only a little more crowded with each passing decade in terms of our daily lives. You can still find a parking spot. But although the population of the USA increases by only about three million people a year, through births and immigration together, each of those three million new Americans will consume on average forty or fifty times as much as a person born in the Third World.
2. Human beings are empirically unequal in intelligence, skills, moral qualities, physique and beauty. It is only some religious or humanistic ideal that suggests an equality at some ontological level that transcends these empirical differences.
3. Equality is closely related to justice and freedom and these have to be balanced against one another. Equality cannot be the sole, comprehensive social ideal. Some social inequalities are necessary in a given society and period of history but should be justified in light of individual freedom, a just society and the common good.
4. Injustice arises when equals are treated unequally, and also when unequals are treated equally (Aristotle).
