Of greatest interest to me is the context or frame-of-reference the biographical material provides for one of Schumpeter's most influential business concepts, "creative destruction," which he introduced in his most popular book, Capitalism, Socialism, and Democracy," first published in 1942. Scholars have divided opinions as to the influences on Schumpeter's development of this concept. They probably include Karl Marx, Friedrich Nietzsche, and Werner Sombart.

According to Schumpeter, there is a "process of industrial mutation -- if I may use that biological term -- that incessantly revolutionizes the economic structure from within, incessantly destroying the old one, incessantly creating a new one. This process of Creative Destruction is the essential fact about capitalism. It is what capitalism consists in and what every capitalist concern has got to live in." He goes on to explain, "The first thing to go is the traditional conception of the modus operandi of competition. Economists are at long last emerging from the stage in which price competition was all they saw. As soon as quality competition and sales effort are admitted into the sacred precincts of theory, the price variable is ousted from its dominant position. However, it is still competition within a rigid pattern of invariant conditions, methods of production and forms of industrial organization in particular, that practically monopolizes attention. But in capitalist reality as distinguished from its textbook picture, it is not that kind of competition which counts but the competition from the new commodity, the new technology, the new source of supply, the new type of organization (the largest-scale unit of control for instance) - competition which commands a decisive cost or quality advantage and which strikes not at the margins of the profits and the outputs of the existing firms but at their foundations and their very lives." (from "The Process of Creative Destruction," 1942) There are countless examples of applications of this concept, notably Jack Welch's determination to "blow up" GE after he succeeded Reginald Jones as CEO.
