Much like the collapse in employment, the collapse in GDP numbers is unprecedented.
Obviously GDP is not the best measurement of an economy, but it's the only one that everyone uses.

Everyone has heard of GDP, but most don't know how it is calculated.
As a simple mathematical equation, it is written as M * V = P * Q, where M is money supply, V is velocity, P is price inflation and Q is real GDP.
The two numbers on the right side of the equation (the outputs) have been mostly stable for nearly a decade, but the first two numbers (the inputs) are seriously distorted, and indicate that something is chronically amiss.

The GDP report came out this morning, and it wasn't good.
