Debt Burdens--Stream of Consciousness

If we expect a reversion to the mean for interest rates in the looming world order of large budget deficits and a more risky government fiscal profile compromised by humongous national debt where does that take us? Intuitively you figure borrowing rates eventually will land somewhere in the mid to maybe high-single digits. They can't stay as low as post 2002 period, but they won't go as high as the early 1980s--the salad days for investing in money market accounts and bank CDs.
