George Stigler and Gabriel Kolko are associated with the theory that eventually, govenment regulatory agencies come to be captured by the industry that the agency is charged with regulating.
At the time of the exchange documented below, Wendell Willkie was the head of an electric utility, and Lilienthal was one of the heads of the TVA, which was in the process of taking customers away from Willkie’s utility. Willkie’s argument to Lilienthal is consistent with the capture theory. (But that Lilienthal pushed ahead with his plans, might be seen as inconsistent with the theory.)
(p. 182) Lilienthal set up a meeting in early October 1933 at the Cosmos Club in Washington, the club being, in Lilienthal’s words, “about as neutral a ground as we could think of.”
. . .
(p. 183) Willkie tried yet another tack. No one, he argued to Lilienthal, went into government without the intention of going into the private sector later. The private sector, after all, was where the business lived. If Lilienthal was too nasty, then he was not likely to find work at private utilities companies. Lilienthal was, by his own admission, “pretty badly scared” by the time he left the Cosmos.
