Boe....how does what we owe social security debt fit in to this picture?
since we are NOW having to cash in what was loaned, so to pay for the above expectations of seniors having to retire, coupled with also pulling in less in SS taxes due to more unemployed or retired?
Is what we have to pay back to SS, in that figure of annual interest payments or $700-900 billion? Will drawing on SS verses surplus of SS make those figures higher or do you think SS shortages are included somehow, and my concerns of a 1 trillion dollar or a 1.2 trillion annual interest payment as the possible outcome?
The SS lock box is stuffed with IOUs that have to be repaid. As long as there is a surplus, those IOUs can be held. But once we need that money to cover current retirees, it has to be redeemed.
Given that this money has already been spent, there are two alternatives: Raise Taxes or Borrow More Money. The latter involves taking these IOUs Treasuries and selling them in the external market, which requires real interest payments to third parties. As such parties are concerned about the U.S.'s growing debt burden, they are demanding a bigger risk premium in the interest rate.
The increase in total annual interest, to my understanding, is the cash interest to be paid out externally. It is based on the huge increases in deficit spending in the current administration's budget, as well as the increased interest rate on the recycling of outstanding debt. As this is cash related, I don't think it covers the IOUs in the lockbox. (If someone else has different info, I'd appreciate seeing it - as well as a source link.)
Your concerns that annual interest will exceed $1B are Very Valid. The Obama forecasts assume incredibly optimistic GDP growth (which is why the CBO predicts worse deficits, it lowered those estimates). A decade of total deficit spending each year combined with cumulative debt and higher interest rates makes $1B the likely scenario.
