The war validated Randolph Bourne's axiom that "war is the health of the state," but it killed Bourne, who died in December 1918 from the influenza epidemic the war unleashed. Today, as another war is enlarging government's intrusiveness and energizing debate about it, it is timely to remember that war is not the only, or even primary, cause.
Or, more precisely, actual war is not the only cause. Ersatz "wars" - domestic wars on various real or imagined vices - also wound the defense of limited government. So argue David B. Kopel and Trevor Burrus in their essay "Sex, Drugs, Alcohol, Gambling and Guns: The Synergistic Constitutional Effects."
Kopel and Burrus, both associated with Washington's libertarian Cato Institute, cite the 1914 Harrison Narcotics Act, which taxed dealings involving opium or coca leaves, as an early example of morals legislation passed using Congress' enumerated taxing power as a pretext. In 1919, the Supreme Court held that the law "may not be declared unconstitutional because its effect may be to accomplish another purpose as well as the raising of revenue."
The "effect" of suppressing the drug business obviously was its purpose. Nevertheless, the court held that even if "motives" other than raising revenue really explained Congress' exercise of its enumerated power, the law could not be invalidated "because of the supposed motives which induced it."
The court's refusal to reach a reasonable conclusion about the pretext Congress used in this case for trespassing on territory reserved to the states enabled the federal government to begin slipping out of its constitutional leash. In 1922, Chief Justice William Howard Taft warned that Congress could seize control of "the great number of subjects" reserved to the states by the 10th Amendment by imposing a "so-called tax" on any behavior it disapproved: "To give such magic to the word tax would be to break down all constitutional limitation of the powers of Congress and completely wipe out the sovereignty of the states."
So, a 1934 law imposed a $200 tax on the making and transfer of certain guns. Supreme Court Justice Harlan Fiske Stone complacently said that any act of Congress "which, on its face, purports to be an exercise of the taxing power" should be treated as such, without judicial inquiry into any "hidden motives" Congress had.
Congress responded to this "abdication of judicial scrutiny" (Kopel's and Burrus' correct characterization) with the 1937 Marihuana Tax Act, another supposed tax law actually designed not to raise revenue, but to legislate morality by changing behavior. The 1951 Revenue Act taxed "persons engaged in the business of accepting wagers" and required them "to register with the Collector of Internal Revenue." The IRS was becoming the enforcer of laws to make Americans better behaved, as judged by their betters in the federal government.
There have been equally spurious uses of Congress' enumerated power to regulate interstate commerce. In 1903, the court upheld as a valid exercise of that power a law suppressing lotteries by banning the interstate transportation of lottery tickets. Dissenting, Chief Justice Melville Fuller argued that the power to regulate persons and property in order to promote "the public health" and "good order" belongs to the states.
Seven years later, the Commerce Clause was the rationale for the Mann Act, banning the transportation of females for "prostitution or debauchery, or for any other immoral purpose" - including, it turned out, noncommercial, consensual sex involving no unhappy victim.
Today, Congress exercises police powers never granted by the Constitution. Conservatives who favor federal "wars" on drugs, gambling, and other behaviors should understand the damage they have done to the constitutional underpinnings of limited government.
