The richer a nation becomes, the fewer its children, and the sooner it begins to die. Societies organized to ensure the maximum pleasure, freedom, and happiness for all their members are, at the same time, advancing the date of their own funerals. Fate may compensate the Chinese, Islamic, and Latin peoples for their hardships and poverty in this century with the domination of the earth in the next.
Ironically, the unmentioned India is likely the future. (Or AI will take over.)
