Engineers and scientists will never make as much money as business executives.
Now a simple mathematical proof that explains why this 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

Solving for money, we get:

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.

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