For everybody else, life might not have been perfect, but it was a lot better in many ways than life is today. It wasn't shown on screen, but they'd presumably gotten rid of an awful lot of horrible genetic diseases, and probably eradicated poverty by ensuring everybody has at least the minimum intelligence level required to make a decent living.
Oh, and also: everyone was pretty.
The blind watchmaker has done a pretty good job so far, my vote is on letting the guy continue without messing with the mechanism until wel really understand how it works.
The whole picture reminds me of guys with hammers that try to 'improve' a jet engine or a computer. If this is an act of reverse engineering a piece of software, and I believe there are enough parallels with the computer world to justify using that term then you're looking at the equivalent of knowing a few interesting peeks and pokes and the basic opcodes but you are still far away from 'grokking' the program as a whole, so any modifications you make can have consequences beyond what you currently understand.
So all we have to do to eliminate poverty is to get rid of the stupid people?
