John F. Kennedy in his Economic Report of the President from January 1963:
Tax reduction thus sets off a process that can bring gains for everyone, gains won by marshalling resources that would otherwise stand idle—workers without jobs and farm and factory capacity without markets. Yet many taxpayers seemed prepared to deny the nation the fruits of tax reduction because they question the financial soundness of reducing taxes when the federal budget is already in deficit. Let me make clear why, in today’s economy, fiscal prudence and responsibility call for tax reduction even if it temporarily enlarged the federal deficit—why reducing taxes is the best way open to us to increase revenues.
John F. Kennedy in his Tax Message to Congress on January 24, 1963:
In short, this tax program will increase our wealth far more than it increases our public debt. The actual burden of that debt–as measured in relation to our total output–will decline. To continue to increase our debt as a result of inadequate earnings is a sign of weakness. But to borrow prudently in order to invest in a tax revision that will greatly increase our earning power can be a source of strength.
