"It is no accident that successful businessmen are often asto..." — Ernst F. Schumacher quote meaning

It is no accident that successful businessmen are often astonishingly primitive; they live in a world made primitive by this process of [reducing everything to the question of profit]. They fit into this simplified version of the world and are satisfied with it. And when the real world occasionally makes its existence known and attempts to force upon their attention a different one of its facets, one not provided for in their philosophy, they tend to become quite helpless and confused. They feel exposed to incalculable dangers and ‘unsound’ forces and freely predict general disaster. As a result, their judgments on actions dictated by a more comprehensive outlook on the meaning and purpose of life are generally quite worthless. It is a foregone conclusion for them that a different scheme of things, a business, for instance, that is not based on private ownership, cannot possibly succeed. If it succeeds all the same, there must be a sinister explanation.
