Engineers and scientists will never make as much money as business executives. Now a rigorous mathematical proof that explains why this is true:
Postulate 1: Knowledge is Power.
Postulate 2: Time is Money.

As every engineer knows,

Work/Time = Power

Since Knowledge = Power, and Time = Money, we have:

Work/Money = Knowledge

Solving for Money, we get:

Work/Knowledge = Money

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

Conclusion: The Less you Know, the More you Make.

Note: It has been speculated that the reason why Bill Gates dropped out of Harvard's math program was because he stumbled upon this proof as an undergraduate, and dedicated the rest of his career to the pursuit of ignorance.
