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.
