Which US President said this?

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.

If you guessed George W. Bush or Ronald Reagan, you would be dead wrong!  The above was part of the Economic Report of The President from 1963.  The President....John Fitzgerald Kennedy!  Arthur Laffer longs for the days of Kennedy and Hubert H. Humphrey leadership in the Democrat(ic) party and explains why in today's Wall Street Journal.

If only more of today's leaders thought like JFK. Sadly, in the debate over whether to extend the 2001 and 2003 tax cuts, and if so whether the cuts should be extended to those people who are in the highest tax bracket, there is a false presumption that higher tax rates on the top 1% of income earners will raise tax revenues.

Anyone who is familiar with the historical data available from the IRS knows full well that raising income tax rates on the top 1% of income earners will most likely reduce the direct tax receipts from the now higher taxed income—even without considering the secondary tax revenue effects, all of which will be negative. And who on Earth wants higher tax rates on anyone if it means larger deficits?

Since 1978, the U.S. has cut the highest marginal earned-income tax rate to 35% from 50%, the highest capital gains tax rate to 15% from about 50%, and the highest dividend tax rate to 15% from 70%. President Clinton cut the highest marginal tax rate on long-term capital gains from the sale of owner-occupied homes to 0% for almost all home owners. We've also cut just about every other income tax rate as well.

During this era of ubiquitous tax cuts, income tax receipts from the top 1% of income earners rose to 3.3% of GDP in 2007 (the latest year for which we have data) from 1.5% of GDP in 1978. Income tax receipts from the bottom 95% of income earners fell to 3.2% of GDP from 5.4% of GDP over the same time period.

Emphasis mine.  But how can we "afford" these tax cuts the progressive left asks?  Easy and Laffer has the historic data to back it up!

When President Kennedy cut the highest income tax rate to 70% from 91%, revenues also rose. Income tax receipts from the top 1% of income earners rose to 1.9% of GDP in 1968 from 1.3% in 1960. Even when Presidents Harding and Coolidge cut tax rates in the 1920s, tax receipts from the rich rose. Between 1921 and 1928 the highest marginal personal income tax rate was lowered to 25% from 73% and tax receipts from the top 1% of income earners went to 1.1% of GDP from 0.6% of GDP.

So cutting the tax rate ALMOST DOUBLED what the "rich" paid in taxes?  Whodathunkit?  Well anyone who had taken an Economics 101 class wouldathunkit honestly.....and just to prove that was not an anomaly......

Or perhaps you'd like to see how the rich paid less in taxes under the bipartisan tax rate increases of Presidents Johnson, Nixon, Ford and Carter? Between 1968 and 1981 the top 1% of income earners reduced their total income tax payments to 1.5% of GDP from 1.9% of GDP.

Then Laffer goes into the historical reasons why you do not do what this Congress is hell bent on doing - raising taxes in order to "make up" their budgetary shortfalls.

The Great Depression was precipitated by President Hoover in early 1930, when he signed into law the largest ever U.S. tax increase on traded products—the Smoot-Hawley Tariff. President Hoover then thought it would be clever to try to tax America into prosperity. Using many of the same arguments that Barack Obama, Nancy Pelosi and Harry Reid are using today, President Hoover raised the highest personal income tax rate to 63% from 24% on Jan. 1, 1932. He raised many other taxes as well.

President Roosevelt then debauched the dollar with the 1933 Bank Holiday Act and his soak-the-rich tax increase on Jan. 1, 1936. He raised the highest personal income tax rate to 79% from 63% along with a whole host of other corporate and personal tax rates as well. The U.S. economy went into a double dip depression, with unemployment rates rising again to 20% in 1938. Over the course of the Great Depression, the government raised the top marginal personal income tax rate to 83% from 24%.

Is it any wonder that the Great Depression was as long and deep as it was? Whoever heard of a country taxing itself into prosperity? Not only did taxes as a share of GDP fall, but GDP fell as well. It was a double whammy. Tax receipts from the top 1% of income earners stayed flat as a share of GDP, going to 1% in 1940 from 1.1% in 1928, but at what cost?

Emphasis again mine.  The rich do not "absorb" these tax increases as many on the left assume.  They have the expendable income to make sure that their income is sheltered from the tax man.  Just ask former Democrat(ic) Presidential nominee Senator John Kerry...

He (Senator Kerry) bought and housed his $7 million yacht in Rhode Island instead of Massachusetts, where he is the senior senator and champion of higher taxes on the rich, avoiding some $437,500 in state sales tax and an annual excise tax of about $70,000.

If they manufacture a product the cost of that tax gets passed on to the consumers in the form of higher prices.  IT IS HUMAN NATURE.  Because of that, in their race to "punish the rich" the left ALWAYS ends up punishing the working classes that they purport to want to save.

If the left were truly so concerned about making sure that the lower and middle classes prospered, they would cut the burden on the job creators of this country....and those job creators never come out of the lower classes and rarely come out of the middle class.  Cut the burden on the rich and watch the lower and middle classes thrive.  It is an economic FACT that can not be ignored.
