Before its over, Obama's going to run up the debt to over $20 TRILLION.
The Fed has artificially driven down interest rates... They print money and buy TBills with the money. Less TBills drives up the price, which lowers the yield. I don't see how they can keep it up for the long term. Historical rates are closer to 5% than the almost 0% we are paying on the debt now. At 5% of $20T, the interest alone will cost $1T.
To put that in perspective, $1T is roughly what the sum of all personal and corporate income tax receipts last year. Every dollar of taxes would go to paying interest payments on the debt that Krugman and Reich and other left wing economists propose we increase even more.
The government gets income from FICA type taxes as well.
Medicare is running at massive deficits. The prescription drug benefit added by Bush and Republicans make the situation even worse. If we repealed the program, Medicare would still be running massive deficits. The deficits are covered by borrowing $trillions from China and anyone else willing to buy TBills.
Social Security has run a surplus since the 1980s. The surplus funds responsibly invested in the safest investment in the world, you guessed it, TBills. The funds went into the treasury each year and got spent. As more boomers retire, SS was expected to start taking in less than it needs to pay out in 2016. But it's been spending more than it takes in since 2010. The govt. owes itself interest on the TBills owned by the SS trust fund, so the program is "technically" growing, tho not for long. On a cash flow basis, the shortfall was borrowed from China and anyone else who would buy a TBill. That SS tax cut Obama forced on us was effectively a $120B raid on the trust fund; it's going to run out that much sooner than it otherwise would.
Krugman is downright dangerous. At $16T of debt, we would have to TRIPLE everyone's income tax to pay it down to $6T over 10 years. Taxes are about $1T now, including corporate. At 3x, we'd have $1T to cover the red ink govt. insists on, and another $1T to pay down the actual debt.
Tax the rich? They're already paying 43%, including the recent tax hike and the one in ObamaCare. 3x that is more than a 100% tax rate, or not possible.
Elections have consequences. Taking Krugman's advice will hasten our demise.
