"To understand the power elite
we must attend to three major keys: I.. . . .the psychology of the several
elites in their respective milieux. In so far as the power elite is composed
of men of similar origin and education, in so far as their careers and
their styles of life are similar, there are psychological and social bases
for their unity, resting upon the fact that they are of similar social
type and leading to the fact of their easy intermingling. . .
II. Behind such psychological
and social unity as we may find, are the structure and mechanics of those
institutional hierarchies over which the political directorate, the corporate
rich, and the high military now preside. The greater the scale of these
bureaucratic domains, the greater the scope of their respective elite's
power. . .
III. The unity of the power
elite, however, does not rest solely on psychological similarity and social
intermingling, nor entirely on the structural coincidences of commanding
positions and interests. At times it is the unity of a more explicit co-ordination"
(The Power Elite, 1956, p. 19).
