To become a king you must be cruel. You must stake property and kill to defend it. You must make peasants to step on and aristocrats to demonstrate the ideals of what one can Aspire toward. Make the rich richer and the poor poorer. Keep everyone divided and at each other's throats blaming each other instead of you. If you live in such a society it is no mistake. You find yourself in a class because someone created the class for you to fall into. You are not free you're not equal this is by Design.  If you are too stupid or too weak to change the design then you are doomed to repeat the mistakes of your past.
