Like most ideas created in the moment, most are not useable...
Afghanistan (and other 3rd World Countries) used a system, probably still do, that eliminated most of the corruption in the vast lower echelons of government.
For every function, there were at least 3 people part of that function.
It cost too much to bribe everybody, and the others would repost any deviation from the rules not paid for...so it eliminated a good deal of the corruption.
As well as taking a month to, say, get a visa renewed instead of a few days. Drawback to that anti-corruption system is the massive non-speed govt worked at.
We have many solutions now to world hunger, etc, but they have impractical sides too. If everyone has food and shelter, and free med care, the bored population of billions would take to burning, killing, and torturing each other just for entertainment.
Sounds like fun...
