Your figures are a little off. Bush increased the debt from 5 trillion to 12 trillion from Oct 2001 to Sep 2009. Obam's first 8 months were under the BUSH budget. So Bush increased the debt 140%. Obama has increased the debt 33%.
42 Presidents accumulated 5 Trillion while 43 and 44 were able to triple the debt in 12 years with no end in sight. Something has to give here and while taxing the rich may "help" it is certainly not enough nor do I agree with an increase in taxes without reduction in spending.
Cut the spending- 1. We have inflated Defense Budget
2. Import drugs from other countries and let people on Medicare, Medicaid.
Tricare and Veterans. Open up the system for people to choose Govt sponsored health care or keep your private insurance if you can afford.
