These are funny, about the Bush 2001 tax cuts

Under President Bush's plan, an average family of four's inflation-adjusted disposable income would increase by $4,544 in fiscal year (FY) 2011, and the national debt would effectively be paid off by FY 2010. 

The plan would save the entire Social Security surplus and increase personal savings while the federal government accumulated $1.8 trillion in uncommitted funds from FY 2008 to FY 2011, revenue that could be used to reform the Social Security and Medicare systems and reduce the payroll tax.

To date, most other analyses of President Bush's tax plan have relied on "static" budget estimates.6 Unfortunately, those types of studies are often misleading.

For example, static analysis of both the Kennedy and Reagan tax cuts suggested that they would reduce federal revenue significantly, when actually they resulted in substantial increases in tax revenues.

Often misleading, hahaha

And then there are the 1993 Clinton tax hikes, and the efforts of Heritage to rewrite history..

Under President Bill Clinton, the U.S. economy grew for 32 straight quarters. During that time, overall annual real economic growth averaged 3.8 percent, and each month, an average of nearly 240,000 net new jobs were created. Under President George W. Bush, the U.S. economy grew for only 25 straight quarters. And during that expansion, economic growth averaged just 2.6 percent, and only 86,000 jobs were created per month.

These are difficult facts for the right wing to explain. After all, President Clinton did the one thing that right-wing, supply siders say you absolutely cannot do if you want to have good economic outcomes—he raised taxes. And for his part, President Bush did the one thing that those same people promise will result in enormous economic gains—he cut taxes. The economic records of the Clinton and Bush presidencies are so clear and so stark that they serve as painful reminders to supply siders everywhere that their ideas have been tested and that they have failed in spectacular fashion.

So it is no surprise that these same supply siders who promised doom and destruction if President Clinton’s rate hikes were passed and who similarly promised dramatic growth and millions of new jobs if President Bush’s tax cuts were passed are now tying themselves in knots trying to prove that they were right all along. Given how well the economy performed under Clinton and how poorly it performed under Bush, this is no easy task. 

Trying to prove something that is so obviously untrue usually requires some pretty acrobatic rhetorical tricks and some funny number crunching. And the newest contribution to this genre of distorted economic history, a report from the Heritage Foundation, contains plenty of both. 

Heritage’s new “policy backgrounder” makes two central claims. First, that the Clinton-era economic boom only began in earnest after he signed a tax cut into law in 1997. And second, that the Bush-era tax cuts, especially the second round in 2003, helped spark an economic “surge.” The first claim is just wrong, relying on a very strange demarcation between the time periods. The second claim is only true if considered completely out of the context of recent history. Fundamentally, the Heritage report is a crude, though valiant, attempt to prove something that most everyone who lived through the past 20 years simply knows to be false. This issue brief delves into the details to expose just how off base the Heritage report is..

Some sympathy is due to the Heritage Foundation. It is not easy or simple to prove a case that is not only so clearly false but is also one that most people already know to be false because they actually lived through it. On top of that, this Heritage report faces the added pressure of trying to repair an economic theory, central to their particular worldview, which has been very badly damaged by recent history. Given all that, it is not surprising that the report relies on miscategorized data and narrow context.
Heritage’s herculean effort notwithstanding, the facts are simple:

• Heritage wrongly claims that the Clinton tax hikes “slowed economic growth.” In fact, in the aftermath of the Clinton tax increase, the economy grew at an impressive 4 percent per year, adding an average of around 240,000 new jobs every month.
  
• Heritage misstates that it was not until after the 1997 capital gains tax rate cut that “growth took off.” In fact, growth rates changed little after the 1997 tax cut, and the pace of job creation actually slowed slightly.
  
• Heritage wrongly concludes that the 2003 Bush tax cuts “prompted a surge in employment.” In fact, job growth following the second round of Bush tax cuts was below the historical average and fell well short of the pace of job creation under Clinton and his higher tax rates.

Another Heritage beauty, dire predictions about the Clinton 1991 tax hikes:

If enacted, the Clinton tax hike will fuel more federal spending, destroy jobs, undermine America's international competitiveness, reduce economic growth, and increase the budget deficit.

Exactly the opposite happened.
