Someone who would be capable of making really well designed mechanics would be just as effective as an engineer, economist or something much more important. But there are such people around that we just don't use. It really just comes down to one number: IQ.
The real problem is that relatively stupid people don't know that they are relatively stupid and there are more of them. They are insecure about being inferior to people of higher intelligence and thus do their best to force handicap and punish anyone with a higher level of ability. I am sure there was some guy at SE that said "hey wait a minute, the numbers are all wrong the game is going to be boring and repetitive once the grandeur wears off" and some relatively stupid artist said "hey what do you know".
If we would accept and understand intelligence and just put everyone's IQ on their record EVERYTHING would be a million times more efficient.
