First, I need to set up some postulates, or things we'll assume as fact.
Postulate 1: Knowledge is Power (Knowledge=Power)
Postulate 2: Time is Money (Time=Money)
Postulate 3: Power=Work/Time (Physics FTW)
So it follows that Knowledge=Work/Money. Solving for Money, we get Money=Work/Knowledge. Thus, as Knowledge approaches zero, Money approaches infinity, regardless of the amount of Work done.
Conclusion: The less you know, the more you make.
I've heard that joke before, and it's not that clever. The logic falls apart if you have basic knowledge of the English language. The definitions of 'power' used in postulate 1 and 2 are completely different; one is synonymous with authority, dominance, influence, omnipotence, etc., whereas the other is a scientific term describing the rate of energy transfer (or transformation)
