BT: In our world I would say there are 4 main classes of human beings ,according to their mind set. Based upon the relationship formed by the human mind with the natural and social environment.
The first group (the masses) are overwhelmed by the psycho-physical waves of reality. Unable to contend with it, this group spends its energy simply trying to exist.
The second group (a type of warrior class ) commands the psycho-physical reality by physical force.
The third (the intellectuals) commands by psychic (mental) force and the fourth (merchants or Capitalists) command by controlling the manufacture and exchange of psycho-physical objects.
The beginning of any age is characterized by great dynamism on all levels – politically, culturally, economically etc. As the new leadership frees the people from the oppressive institutions of the old order. The age peaks in a golden era as the new class overcomes the obstacles of the old order and solidifies its control over society. In time, however, social decline again occurs as the dominant class increases its power at the expense of meeting the basic needs of the people. Social unrest builds as the exploitation becomes more systematized.
At any given time, society will be dominated by the psychology and administration of a particular class. And today we are being dominated by the Capitalist class. As you say ''the global Fat Cats are only interested in protecting their billons and will happily die rich in material excesses.''
But when society starts to feel the exploitation by this Capitalist class, there will be a mass movement which will emerge to remove this dominating Capitalist class. Moved by the voice of the Intellectual class, the masses, lead by the 'labourer' class, will eliminate this 'elite' Capitalist class. Then again we will see the Social cycle move, and again a new class will attain dominance
