Engineers and Scientists will never make as much money as business 
executives. Now a rigorous proof that explains why that is true:

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

As every engineer knows,
 
                             Work
                             ----- = POWER
                             Time

Since Knowledge = Power,
And Time = Money, we have

                             Work
                             ------ = KNOWLEDGE
                             Money

Solve for Money,

                             Work
                             ---------- = MONEY
                             Knowledge

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

Conclusion: The Less you Know, the more you Make!

N.B.: It has been speculated that the reason 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.
