In my opinion our own country and every other advanced country in the world is heavily dependent upon a certain type of man. This man may be an executive, a scientist, a general or a coal miner—but he is the man who works harder than there is any immediate need for him to work and harder than any of the incentives offered him by society justify. He does this because work offers him an outlet for the tensions a hostile environment has built up in him and society exploits him to its benefit.”
