First 224 years of existence: 5.674 trillion dollars
Next 8 Bush years: 4.350 trillion dollars
Next 7 Obama years: 8.126 trillion dollars
Compare what we've done in the last 15 years to what we did in the first 224 years. We've more than tripled in the last 15 years what it took 224 years to accumulate in debt.
To be lazy and use stereotypes, democrats spend too much and republicans tax too little. The truth is that both parties spend too much and tax too little. The current war spending is not sustainable. The current tax rates are not sustainable. Social Security and Medicaid are about to explode in expenditures. You simply cannot cut this level of debt by only cutting spending or only raising taxes. It will take substantial efforts on both ends to put things in order, and then it will take disciplined restraint and political will to stay on course over several decades to begin to fix this process.
Frankly, our politicians are not up to the challenge. Their incentive is re-election every 2 or 4 years, and this type of outlook is incompatible with the long-term approach necessary to fix what an utter mess the national finances have become.
