In addition to this, it may be said that the contrast between the culture represented by the modern white and that of primitive man is far more fundamental than that between the ancients and the people with whom they came in contact. Particularly, the methods of manufacture have developed so enormously, that the industries of the primitive people of our times are exterminated by the cheapness and large quantity of the products imported by the white trader, because primitive man is unable to compete with the power of production of the machines of the whites, while in olden times the superior hand-product rivalled the hand-product of a lower type. When a day’s work suffices for obtaining efficient tools or fabrics from the trader, while the manufacture of the corresponding implement or material by the native himself would have required weeks, it is but natural that the slower and more laborious process should be given up speedily. It must also be considered that in several regions, particularly in America and in parts of Siberia, the primitive tribes are swamped by the numbers of the immigrating race, which is crowding them so rapidly out of their old haunts that no time for gradual assimilation is given. In olden times there was certainly no such immense inequality in numbers as we observe in many regions nowadays. We conclude, therefore, that the conditions for assimilation in ancient Europe were much more favorable than in those countries where in our times primitive people come into contact with civilization. Therefore we do not need to assume that the ancient Europeans were more gifted than other races which have not become exposed to the influences of civilization until recent times (Gerland, Ratzel).
