Calvin Coolidge Comments on the Effects of Reducing and Eliminating Taxes- From Sixth Annual Message- December 4, 1928:

"Four times we have made a drastic revision of our internal revenue system, abolishing many taxes and substantially reducing almost all others. Each time the resulting stimulation to business has so increased taxable incomes and profits that a surplus has been produced. One-third of the national debt has been paid, while much of the other two-thirds has been refunded at lower rates, and these savings of interest and constant economies have enabled us to repeat the satisfying process of more tax reductions. Under this sound and healthful encouragement the national income has increased nearly 50 per cent, until it is estimated to stand well over $90,000,000,000. It has been a method which has performed the shining miracle of leaving a much greater percentage of earnings in the hands of the taxpayers 'with scarcely any diminution of the Government revenue. That is constructive economy in the highest degree. It is the corner stone of prosperity. It should not fail to be continued."
