The book's most misread idea. Mills' elite does not meet to decide; it does not need to. Recruit from the same strata, school at the same institutions, and circulate the same people through corporation, Pentagon, and cabinet. The command posts will then produce compatible decisions the way parallel rails produce parallel trains.
The claim's power is that it survives every failed hunt for the smoke-filled room. Its weakness, as critics noted, is that the same evidence can describe an establishment's culture rather than its rule.
What Mills actually predicted
Written in 1956, the book reads as an early warning about arrangements later named by others. Eisenhower's 1961 farewell warning about the military-industrial complex arrived five years after Mills mapped the terrain professionally. Where Mills was arguably wrong is as instructive as where he was right. The reading-on page pairs the book with Dahl's pluralist reply and with the later literatures that kept score: power-structure research and elite studies.
Argument questions
What are the "three institutional orders"?
The corporate rich, the military ascendancy ("warlords" in Mills' hotter vocabulary), and the political directorate — the executive branch's command posts. Mills' claim was historical, not eternal. The postwar growth of corporations and of a permanent military establishment had fused hierarchies that were once more separate, and the people atop them increasingly moved between all three.
What did Mills mean by the "middle levels" and "mass society"?
The middle levels, Congress prominent among them, were where classic pluralist politics still visibly happened, but over stakes Mills considered secondary. The big decisions — war footing, economic structure — had moved upward. The mass society below was his bleakest chapter: publics replaced by audiences, opinion increasingly manufactured by media rather than formed in discussion. That diagnosis, more than the elite mapping, is what modern readers find uncomfortably current.
What is the strongest criticism of the book?
Pluralists argued that Mills inferred unified power from co-location; Robert Dahl's Who Governs? is the classic rejoinder. Showing people at command posts is not the same as showing they rule as a bloc. Case studies of actual decisions found messier bargaining. Later readers add that Mills' elite was a snapshot of 1950s WASP institutions. The debate is genuinely unresolved, which is why the reading-on page sends you to both sides rather than declaring a winner.
