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.
