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.
