From McCraw’s discussion of Schumpeter’s legacy:
(p. 496) No country, regardless of how long it has been prosperous, can take permanent affluence for granted. Nor can any company assume its continued existence—as names such as Digital Equipment, Pan American Airways, Pullman, Douglas Aircraft, and the Pennsylvania Railroad remind us. Each of these companies once epitomized the cutting edge not only of its own industry but of American business as a whole. And all are now in the dustbin of history, along with hundreds of thousands of other businesses of all sizes—once as strong as dinosaurs but now just as extinct.
