The theories of Karl Marx has made us to understand that an equal society is possible if the society work in unity. Search has shown that 80% of relationship between societies is strictly bias and profit minded which make it difficult for equal society to exist. The rich hate the poor to reach the class and the poor hate the rich for always staying at the top. A quote says: the rich cannot sleep because the poor are awakes and the poor can not sleep because they're hungry. This are part societies from the pictures of seeing people equal or leadership doubtlessly working towards equal societies. Is any society that practice equality laws and equity for oneness in all shared resource?
So far as the hunger to be at the top continues, every one can never be equal in the society reason being that we all are humans but created differently because there are things you know and you are able to comprehend them perfectly but I may not know even if I try to I may not be as perfect as you are that is just nature for us and coming to the society we are now, the rich wants to get Richer and take home everything without caring about how the poor ones in the society are doing instead they will even see where the poor ones are trying to survive from and still take it from them so there is no relationship between the poor and the rich because Normally, the rich always roll with the rich so there is no place for the poor and that brings about inequality in the society.
