My theory on this, for what it is worth, is that interest rates are as important, if not more important, than the fuel/energy cost, and therefore, as long as interest rates are kept low, the system could go on for quite a while in its current dysfunctional form.
We did the calculation last fall during the Katrina period to the effect that as a percentage of the overall cost of a produce item (peaches), the interest/finance charge was actually more important, as a percent of the selling price, than the fuel cost to produce, transport and sell it.
As further evidence, note in the graph above the price of oil doubled between 1978 and 1979, but it was not until volcker raised interest rates in 1979-1980 that the economy finally slowed down, and people started to use less oil. As you can see from the above, it was not all that much less oil, either. Ultimately the economy went into a hell of a recession, and people started losing their jobs, per the earlier post.
The difference this time around is that even though the price of energy has doubled (actually tripled in the last 2 years) interest rates have stayed low. Part of this is because they were deliberately kept low by Bubblespan, and part of this is because "the market" , that is, the Chinese and Japanese who are loaning out the money, do not perceive much inflation risk, and therefore do not demand higher rates when they lend us money. Also, part of this is the fact that there is a lot of money in the system, as courteously provided by the current liberal government spending policies.
The article cited above talks a lot about the emotional element of this, which is to say that during the 70's there were periods of emotional expectations of inflation that made people demand higher rates.
The chart above shows what Volcker did. During a period of about 18 months, he basically put his foot on the throat of the economy until the disinflation hit and got everything back under control. The reason he did this was that he had a mandate from his bosses (the fatcats that control the economy) who insisted that inflation, and capital deterioration, be brought more under control.
So, how long will the current system go on?
Maybe a long time. It is possible that as long as the Chinese and Japanese accept low interest rates, and as long as copious money keeps flowing out of the US government treasury, things could keep up like this for quite awhile, even if "the peak" passes and oil becomes more expensive. Even if the price goes up, the poor nations will give up their oil first before the wealthy nations, so the system could go on awhile longer.
However, at some point, the lenders will take a look at the situation and start to seriously question whether the US borrowers (government and corporate) are capable of paying back a loan, or whether or not inflation risk is still around. At this point, they will demand higher interest in response to the risk. If you look at interest rates in places like Ecuador and Venezuela, you can see what happens when people lose faith in the government's ability to repay a loan (20-25% interest).
We can be pretty sure that the supply of government red ink will continue indefinitely. Also there is no indication that the fed guy Bernanke will do anything except print bountiful money.
So, there would have to be quite an emotional tipping point before any of this would happen. Also, you can be sure that the longer the delay between now and the tipping point, the more painful the remedy will be.
