It cannot be too often repeated that in this country, in the long run, we all of us tend to go up or go down together. If the average of well-being is high, it means that the average wage-worker, the average farmer, and the average business man are all alike well-off. If the average shrinks, there is not one of these classes which will not feel the shrinkage. Of course, there are always some men who are not affected by good times, just as there are some men who are not affected by bad times. But speaking broadly, it is true that if prosperity comes, all of us tend to share more or less therein, and that if adversity comes each of us, to a greater or less extent, feels the tension.
