Stagflation.
Study. Use the seventies as your starting point.
Give Oz a cigar for posting the word that, I suspect, most of the 20 something college students here haven't heard of and certainly haven't lived through.
"Stagflation", a condition, that by all rules of economics, cannot exist.
But it did.
Rising prices coupled with
decreasing demand.
Look at the debt charts that have been posted. It's no accident that the rising national debt started to explode around 1980. Volcker and Reagan had no choice, to combat "stagflation" caused by the complete "uncoupling" of the dollar from gold under Nixon in 1971, but to tighten monetary supply and deficit spend.
The only reason that inflation hasn't been more pronounced at the consumer level is because of the borrowing and total de-industrialization to places like China.
But now, faced with an unprecedented meltdown, the Fed is at the point where it will have no choice but to lower interest rates to zero. At that point, there will be no incentive for foreign nations to buy up our debt.
At that point you will have stagflation that will make the period of stagflation in the late 1970s look like a walk in the park.
And that equals "game over".
Further, to put a timeframe on a currency collapse, when in a such an untenable situation as we are, is foolish. It can happen overnight. Just ask the Russians or Argentineans.
If I had told you in 1988 that by 1992 there would be no more USSR and Berlin Wall, you'd have thought me nuts as well.
