"If low price is the only basis of competition with rival products, similarly produced, there ensues a cut-throat competition which can end only by taking all the profit and incentive out of the industry. The logical way out of this dilemma is for the manufacturer to develop some sales appeal other than mere cheapness, to give the product, in the public mind, some other attraction, some idea that will modify the product slightly, some element of originality that will distinguish it from products in the same line. Thus,"
Edward L. Bernays
