Dilbert's "Salary Theorem" states that "Engineers and scientists can never
earn as much as business executives and sales people."

This theorem can now be supported by a mathematical equation based on the
following two postulates:

Postulate 1: Knowledge is Power.
Postulate 2: Time is Money.

As every engineer knows: 
    Power = Work / Time

And since: Knowledge = Power
and: Time = Money

It is, therefore, true that

Knowledge = Work / Money

Solving this equation for Money, we get:

Money = Work / Knowledge

Thus, as Knowledge approaches zero, Money approaches infinity, regardless of the amount of Work done.

 
Conclusion: The less you know, the more you make.
