What is good for the poor? I think that the evidence of the last fifty years is clear enough, so that we can say that we know the following: The most effective method of reducing poverty is economic growth. The economic system most likely to generate growth is capitalism. By way of contrast, socialism is ineffective in generating growth, and most likely to produce equality in poverty for most people and wealth for a small elite (the nomenklatura of the Soviet Union and other socialist regimes).
I think we can say that wealth for a small elite has been the effect of U.S. federal policy for some time now.
