First let me say that a society with over 50% conscious people is not going to stay at 50% very long... I believe that it will have an explosive effect... and in a very short period of time that number will become 60-70-80-90%
There is a very interesting book by count Leo Tolstoy called "
The kingdom of God is within you" and it treats the subject of Anarchy too, Christian Anarchy...
In this book his main idea from a society structural point of view is like this:
there are 3 stages of mankind
1. Barbary - man did pretty much whatever his animal urges dictated
2. State - built first around the nucleus of a family evolved to tribe then state. The main characteristic of this stage is "THE LAW", be it sent by God or created by man... the individual of the society had to obey it or face consequences.
Tolstoy said that this level reached its peak in Roman Empire times, some 2000 years ago when the Law reached its full maturity (current law is still based on Roman Law) and it is still the current stage.
Then came Christ and with his teachings showed man kind the third stage in its evolution
3. Christian Anarchy...
Now the main problem was that this stage competed with the previous stage and sometime around 300 AD something happened... The state adopted Christianity and in the process corrupted its message...
Right now the message of Christ is buried under miles of old stage Laws and old style "observance" believing.
Tolstoy goes further and says that although Christ teachings received this blow, they still survived and permeated the society... more and more...
and now they are at the heart of a lot of its members...
You don't need to explain to a normal person that is wrong to kill someone or to steal... they know it in their hearts to be wrong.
Another interesting phenomena is that quality people will start to choose other jobs than the ones regarded as prestigious by the old stage like Army, Administration, Law and such... and this will result in less competent people ending up in those positions... people discontent will rise and when it will peak they will realize that they don't need the old structure anymore.... more will start to practice civil disobedience, tax resistance, etc. They will realize that Nonresistance to evil by force is THE WAY!
They will start becoming better persons and start to create real service to people around them, either by listening to Christ's advice of "the first among you shall be your servant" or by listening to Earl Nightingale advice that "Money comes from service"... either way will do.
Success of this kind of people will inspire... and more will join... people will learn to love, will learn to think for themselves rather than turn on the cesspool in their living room.
Either there will be a progressive realization of this transformation or it will be brought about by calamity... like a nuclear war or some other catastrophically stupid thing that a man with too little brains and too much power at his disposal could do.
