We know that Power is Work divided by Time:

P = W/T

And we know that Knowledge equals Power, and Time equals Money:

K = P , T = $

So, Knowledge equals Work divided by Money:

K = W/$

And Money equals Work divided by Knowledge:

$ = W/K

So, as Knowledge approaches zero, Money approaches infinity:

K → 0 , $ → ∞.

Thus proving, that one with infinitesimally small amounts of grey matter has way too much cash.
