Skill Quotes - page 27
This being the case, industry, skill, frugality, and intelligence can avail the individual only in so far as they are superior to the general level just as in a race speed can avail the runner only in so far as it exceeds that of his competitors. If one man work harder, or with superior skill or intelligence than ordinary, he will get ahead; but if the average of industry, skill, or intelligence be brought up to the higher point, the increased intensity of application will secure but the old rate of wages, and he who would get ahead must work harder still.
Henry George
