It is truism today that “special interests” are to blame for economic problems and corruption. But “special interests” are only a symptom, not the cause of the disease.
In a populist democracy with a mixed economy, every group that participates in the political system is a “special interest”, with the incentive and the power to use the political system to extract benefits for its members at the at the expense of everyone else. Corporations, unions, disease-awareness organizations, “minority” groups, and anyone who organizes around a common cause has the power believes that their fate or cause is more legitimate, important, and “special” than that of everyone else.
The welfare and regulatory systems are the primary means to coercively redistribute property and confer monopoly benefits to various groups. In a mixed economy, everyone is constantly on the defensive against organized groups extracting benefits from him, and on the offensive attempting to use the coercive power of the state to extract benefits from others. Interventionism creates a vicious cycle hardly unique to corporations: first a lobby tries to extract special privileges from some politically neutral group, the group hires lobbyists to defend itself, and ends up using the influence it has gained to extract privileges at the expense of another neutral group, which must defend itself in turn.
The existence of “special interests” is just a symptom of the disease: the growth of government power to a degree that allows those in power to violate our rights and steal our property for the benefits of their constituents. Populist “maverick” politicians who claim that they will “fight special interests” and “change the culture in Washington” are just attempting to subvert the power of the state to favor their particular constituency. Campaign finance regulations are just monopoly privileges created by the political élite to hide corruption from the public and make it more difficult for those without political connections and money to get elected and in order to defend themselves or join in the looting.
The only solution to the problems caused by interventionism is to end interventionism – to separate government and economy. Take away the power of the government, and you will remove both the incentive and the power of the “special interests.” As long as governments try to control people and businesses with laws that go beyond the protection of property rights, the “special interests” will have the incentive to control governments.
