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: Power = Work / Time
Since Knowledge = Power, and Time = Money, we have: Knowledge = Work / Money
Solving for Money, we get: Money = Work / Knowledge
Thus, as Knowledge approaches zero, Money approaches infinity regardless of the Work done.
Conclusion: The Less you Know, the More you Make.
