This statement is utter nonsense: "The amount of taxes that corporations and the top 1% have stolen from the US Treasury by exploiting loopholes, tax havens, and tax cuts." Exploiting loopholes, tax havens, and tax cuts is also known as full compliance with law. It's quite fanciful to complain about full compliance with law by characterizing it as stealing.
This organization,
FlipTheDebt.org, reckons its figure as from 2001, when Congress passed the tax cuts proposed by President George W. Bush, History's Greatest Monster.
Okay, then. So
The Rich! The Rich! have had their taxes reduced by US$2.8 trillion (I visited the website) since 2001, a period of 15 years, and all of that has become debt. But our national debt is US$18 trillion. The debt was US$5.8 trillion in 2001, and US$10 trillion in 2008. What accounts for the rest of the debt, since the money "stolen" by evil corporations and the 1% when they comply with tax law doesn't even reach a quarter of the debt incurred by the United States during their 15-year crime spree?
