If we, human beings, were socially engineering ourselves and our planet all over again, but with the knowledge we now have we would not allow refined sugar, alcohol or cigarettes, to ever be placed on the market. We would not allow false psychiatry which is a pseudo science to exist in any basis whatsoever. We would not allow the drug industry to deliberately blend its drugs with harmful substances in order to poison some and dumb down others for the true purposes of eventual world wide enslavement of the human race.
We would ban public forced schooling where our children are being taught unquestioning obedience to false authority and where they are not being taught to think logically in any area. They are being forced to believe scientism which is a false belief in what some dishonest scientists say rather than in what is empirical evidence. Instead we would home educate our children. Children are being forced to think like schools of fish rather that enabled to draw their own individual logical conclusions.
We would never allow unreasonable man-made law to come into use in our world. We would use natural laws which are constructed upon natural reason which is fixed and immutable. We would use judges selected at random from our communities who would have no political affiliations and who would only be allowed to make a judgement once or twice in their lifetime.
What else would we do differently if we were organising our planet from the beginning?
