    [Milton Friedman] was above all pragmatist, and he emphasized the superiority of the negative income tax over conventional welfare programs on purely practical grounds. If the main problem of the poor is that they have too little money, he reasoned, the simplest and cheapest solution is to give them some more. He saw no advantage in hiring armies of bureaucrats to dispense food stamps, energy stamps, day care stamps and rent subsidies. (Robert H. Frank Milton Friedman The New York Times 23 2549, )
