Professor Ross puts the matter very aptly when he remarks concerning Chinese immigration: "The competition of white laborer and yellow is not so simple a test of human worth as some may imagine. Under good conditions the white man can best the yellow man in turning off work. But under bad conditions the yellow man can best the white man, because he can better endure spoiled food, poor clothing, foul air, noise, heat, dirt, discomfort, and microbes. Reilly can _outdo_ Ah-San, but Ah-San can _underlive_ Reilly. Ah-San cannot take away Reilly's job as being a better workman; but because he can live and do some work at a wage on which Reilly cannot keep himself fit to work at all, three or four Ah-Sans can take Reilly's job from him. And they will do it, too, unless they are barred out of the market where Reilly is selling his labor. Reilly's endeavor to exclude Ah-San from his labor market is not the case of a man dreading to pit himself on equal terms against a better man. Indeed, it is not quite so simple and selfish and narrow-minded as all that. It is a case of a man fitted to get the most out of good conditions refusing to yield his place to a weaker man able to withstand bad conditions."[164] All this is no disparagement of the Asiatic. He is perfectly justified in trying to win broader opportunities in white lands. But we whites are equally justified in keeping these opportunities for ourselves and our children. The hard facts are that there is not enough for both; that when the enormous outward thrust of colored population-pressure bursts into a white land _it cannot let live_, but automatically crushes the white man out--first the white laborer, then the white merchant, lastly the white aristocrat; until every vestige of white has gone from that land forever. This inexorable process is thus described by an Australian: "The colored races become agencies of economic disturbance and social degradation. They sap and destroy the upward tendencies of the poorer whites. The latter, instead of always having something better to look at and strive after, have a lower standard of living, health, and cleanliness set before them, and the results are disastrous. They sink to the lower level of the Asiatics, and the degrading tendency proceeds upward by saturation, affecting several grades of society.... There is an insidious, yet irresistible, process of social degradation. The colored race does not intentionally, or even consciously, lower the European; it simply happens so, by virtue of a natural law which neither race can control. As debased coinage will drive out good currency, so a lowered standard of living will inexorably spread until its effects are universally felt."[165]
