Demand or supply shock?

How does supply make money? Buy stuff and sell it. So lets try looking at the sales price  minus the cost of inputs, consumer prices minus producer prices. When that number is high, suppliers are doing well. When that number plunges, suppliers are losing money.

See the blue line? What does it do just before the crash? It plunges. And it plunges straight down when the oil price jumped to $140 just before the crash.  Transportation costs went through the roof, and that is a supply shock.  Trucking stopped cold, here in California and all over the world. Keynesians are still flogging this issue, but they are simply being fraudulent jackasses. We had a supply shock.
