Any money the government spends must be taxed, borrowed or conjured out of thin air by the Federal Reserve, and that will reduce sound private investment. Obama has no real wealth to inject into the economy. He can only move around existing money while inflation robs us of purchasing power. Meanwhile, private investors who might have produced a better engine, battery, computer, cancer treatment or other wealth-creating and life-enhancing innovations hold back for fear that big government will undermine productive efforts.
