Talk to the recession daters on the causes

Economists insist they have uncovered the cause of the blue bar. 

The proximate cause was the recession daters, ask them: "How did those oil spikes and dips mark the beginning and end of the blue bar so well?"

It is not a coincidence, it was done by bean counters many of whom are known  personally by the economists.  The issue is what caused the blue bar, go to the source of the issue quit trying to bring up fantasies.

We get the same sudden stop in the great depression. how the financiers in DC cause the sudden stop? Has any ever asked some American person at the time, "why did you suddenly stop".

If you had asked that person, at the time, you get the truth, we suddenly stopped because traffic was jammed up everywhere, a result due to the initiation of FCC and broadcast networks, by Hoover, in 1928. Roads could not handle mass marketing, we crashed.
