"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:

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

As every engineer knows:
Power = Work / Time

Since:
Knowledge = Power
Time = Money

It follows that:
Knowledge = Work/Money.

Solving for Money, we get:
Money = Work / Knowledge.

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