Look at growth in GDP from 2000-2010:
2000: 3.7%
2001: 1.2%
2002: 1.3%
2003: 1.4%
2004: 3.4%
2005: 2.6%
2006: 2.9%
2007: 2.8%
2008: 0.0%
2009: 2.6%
2010: -2.0%
Compared to tax revenue collected:
Tax revenue for 2000: $2.03 Trillion
Tax revenue for 2001: $1.99 "
Tax revenue for 2002: $1.85 "
Tax revenue for 2003: $1.78 "
Tax revenue for 2004: $1.88 "
Tax revenue for 2005: $2.15 "
Tax revenue for 2006: $2.41 "
Tax revenue for 2007: $2.57 "
Tax revenue for 2008: $2.52 "
Tax revenue for 2009: $2.10 "
Tax revenue for 2010: $2.16 "
Notice how revenues track GDP. offset by about a year? Revenue jumped from 2004-2006, which is the same timeframe the economy was growing close to 3%. Revenue likewise dropped as of 2009, the year after GDP flatlined. Changes to tax revenue track changes to GDP naturally.
My point being: Tax collections go up over time. By reducing tax rates, you cause a ONE TIME increase to GDP, but a permanent loss in revenue due to the lower rates. Over time, that adds up.

CBO estimates a cumulative deficit of $6.2 trillion from 2002-2011; with a price tag of $2.02 trillion, the Bush tax cuts, including last year's extension, are responsible for almost one-third of the shortfall.

Pending policies that will add to the federal deficit:
Extension the 2001 and 2003 Bush tax cuts scheduled to expire in December 2012: $2.84 trillion plus another $505 billion in debt service fees, totaling $3.35 trillion added to the deficit between 2013 – 2022
Extension of 80 other tax provisions, many of which expired in December 2011, including research and experimentation tax credit: $839 billion plus another $173 billion in debt service fees, totaling $1 trillion added to the deficit between 2013 – 2022
Extension of the Alternative Minimum Tax exemptions: $804 billion plus another $133 billion in debt service fees, totaling $937 billion added to the deficit between 2013 – 2022
Continuation of existing Medicare reimbursement rates to physicians: $316 billion plus another $56 billion in debt service fees, totaling $372 billion added to the deficit between 2013 – 2022
Cancellation of sequester cuts mandated by the Budget Control Act: $984 billion plus another $187 billion in debt service fees, totaling $1.2 trillion added to the deficit between 2013 – 2022
Although I'm sure your analysis is better then that of the CBO. [/sarcasm]
