What was predicted about 100 years ago is becoming true before our very eyes. The truth is not fair, egalitarian, or "nice" but there it is for everyone to see.
In The Revolt Against Civilization (1922), Stoddard put forward the theory that civilization places a growing burden on individuals, which leads to a growing underclass of individuals who cannot keep up and a "ground-swell of revolt". Stoddard advocated immigration restriction and birth control legislation to reduce the numbers of the underclass and promoted the reproduction of members of the middle and upper classes. He considered social progress impossible unless it was guided by a "neo-aristocracy" from the most capable individuals that was reconciled with the findings of science rather than based on abstract idealism and egalitarianism. Stoddard was one of several eugenicists who sat on the board of the American Birth Control League.
Stoddard argued that race and heredity were the guiding factors of history and civilization and that the elimination or absorption of the "white" race by "colored" races would result in the destruction of Western civilization. Like Madison Grant in The Passing of the Great Race, Stoddard divided the white race into three main divisions: Nordic, Alpine, and Mediterranean. He considered all three to be of good stock and far above the quality of the colored races but argued that the Nordic was the greatest of the three and needed to be preserved by way of eugenics. He considered most Jews to be racially "Asiatic" and argued for restricting Jewish immigration because he considered them a threat to Nordic racial purity in the US. He warned that US was being "invaded by hordes of immigrant Alpines and Mediterraneans, not to mention Asiatic elements like Levantines and Jews." Stoddard's racist beliefs were especially hostile to black people. He claimed that they were fundamentally different from other groups, they had no civilizations of their own, and had contributed nothing to the world. Stoddard opposed miscegenation, and said that "crossings with the negro are uniformly fatal". During a 1921 speech in Birmingham, Alabama, President Warren G. Harding praised the book.
