The normal individual very naturally regards all industry from his own narrow point of view. He is inclined to feel that his business is the hub of industrial activity, that it is essential to the welfare of society, and that it even deserves encouragement at the hands of the government; and this feeling he often has regardless of the best interests of society. A short wheat crop with high prices may bring joy to the wheat farmer, though it may bring distress to multitudes of consumers. Likewise, the glaziers in the neighborhood of numerous greenhouses may welcome a severe hailstorm as a blessing, when obviously it is detrimental to society as a whole. Even those whose special duty it is to regard industry from the social point of view often fall into the same error. Every winter metropolitan newspapers view heavy falls of snow as godsends to the unemployed men of the cities, who, as a result, are able to find work cleaning streets and sidewalks. Such erroneous notions arise from the practices of modern society, in which each individual produces not for his own direct consumption, but for the markets. It would be different if each supplied his own wants directly by his own labor. The wheat farmer would view a short crop with alarm; the glazier would see no blessing in a hailstorm that compelled him to repair his own greenhouse; nor would the residents of any city regard a heavy snowfall as a godsend if each man were compelled to shovel the snow from his own doorway.
