Business is a pursuit of profits, and profits are to be had from profitable sales, and profitable sales can be made only if prices are maintained at a profitable level, and prices can be maintained only if the volume of marketable output is kept within reasonable limits; so that the paramount consideration in such business as has to do with the staple industries is a reasonable limitation of the output. "Reasonable" means "what the traffic will bear"; that is to say, "what will yield the largest net return."
