One cynical view of economic regulators is that eventually they are "captured" by the interests that they are supposed to regulate. Bruce Baugh explains
All of this leads to the point where the regulatory agency may bristle and grr for the popular press, but its day-to-day business is strongly congruent with the interests of its subjects.
