Greenspan Supports a Tax Cut
Federal Reserve Chairman Alan Greenspan yesterday endorsed the idea of a major federal tax cut as not only fiscally prudent but also necessary.
Citing the huge increases projected in federal budget surpluses, Greenspan told the Senate Budget Committee that his earlier cautions against cutting taxes are no longer valid. The looming surpluses have "reshaped the choices and opportunities before us," he said, noting that the federal debt could be paid before the end of the decade and there would still be money left over, barring a major and prolonged recession.
If the surpluses don't end when the debt does, there could be a serious economic disruption, Greenspan said. That makes large tax cuts essential, he indicated.
