Wayland Way

The laborer may sometimes feel like complaining, that the merchant has an easy time sitting at his desk, while he is sweating at his hard toil; that the merchant rides in his carriage, while he trudges on his weary way afoot; that the merchant is rich, while he is poor. But if he considers how a hundred merchants fail, where one succeeds; how intense and wearing is the merchant's brainwork; how sickening often amid his perplexities, is the showy style of his mode of living; and above all, how intimately connected are the services of the mercantile class with both the wages which he, the laborer earns, and the cheapness of everything he buys in the market for his support, he will hush his complaint, under the conviction that no lot in life is free from its trial, and that the interests of men of different occupations are so woven together that adversity to one class is adversity to all, and true prosperity for one is prosperity for all.
