"To me, there are multifarious forces at work in government departments which are different from those in private business; the responsibility to and necessary interference of Congress, the responsibility to the President, to defined over-all controls, have little parallel in private business. The power politics of government departments are radically different from the power politics of private companies. The existence of pipe lines into Congress strengthens the bureaucracy against the chief executive of the particular subdivision of government. It may strengthen it against the President of the United States or Congress itself. Dimock himself points out how easily government bureaucracies develop organized opposition to policies involving change. This opposition may in substance, though not in form, sabotage all change which appears to threaten the security of the bureaucracy. Power politics, of course, exists in large private companies; but the urge to expand functions and simultaneously to defend what exists seems to me radically less in the case of well-run, large, private industry than in the case of big departments of the government. The quantitative difference becomes a qualitative change."
