Here's something you may not know: George W Hoover could have easily paid off the entire federal debt during his administrations -- twice.
When Bush Jr. took office in 1Q2001, federal receipts were 20.7% of GDP. (Today they are 17.0% of GDP.)
Had federal revenues remained at that level, it's easy to calculate the additional federal revenue that would have come in, using this GDP data.
The answer: an additional $10,820 billion dollars.
When Bush Jr came into office, the total federal debt was $5.7 trillion. When he left office in January 2009 it stood at $10.62 trillion.
Hence, had Bush not decided the surplus was "the people's money," and gave it all to (rich) people, the entire debt would have been easily paid off, with plenty of money left over for wars, killing people, Medicare expansion (Part D), etc.
No conservative gave a crap them. Don't let them tell you they give a crap now.
PS: While Hoover Jr doubled the debt, Reagan increased it by 150%.
