Engineers and scientists will never make as much money as salespeople.
Now a rigorous mathematical proof 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.
