"Strange business," said Lasher. "This crusading spirit of the managers and engineers, the idea of designing and manufacturing and distributing being sort of a holy war: all that folklore was cooked up by public relations and advertising men hired by managers and engineers to make big business popular in the old days, which it certainly wasn't in the beginning. Now, the engineers and managers believe with all their hearts the glorious things their forebears hired people to say about them. Yesterday's snow job becomes today's sermon."
