Rolling over our current national debt at the current rates will make the debt servicing costs too high relative to tax income. So either rates cannot stay high indefinitely, or inflation will continue until debt is smaller compared to tax income. In both cases money becomes cheap. The average maturity on debt is 5 years which is where I got that time scale, but this is also in line with previous cycle lengths-- you can't find many times where the fed has waited longer to cut rates. Debt has also never been this high as a percent of GDP, so more pressure from that shouldead to faster policy changes.
Yes, because after correcting for irrational exuberance and the economy being in a holding pattern for 2 years all the next politician has to say is that they alone can fix the economy by lowering rates. They will then install a dummy head of the Fed that will play along.
