The theories of Karl Marx...
You have not read Marx's Capital, in the same way that almost no one has read it. The garbage of labor theory of value, their taste for commissaries or thinking that in that ideal communist society instead of being specialized in a job, we would change jobs just like gender fluid people change gender are just plain bullshit.
...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?
I don't know what world the panorama you paint is from, but it certainly isn't from this one. In this world we will never be equal, and that's not a bad thing, the world is the way it is. What we have to be is equal in rights and tend to try to equalize in opportunities, not in results. Although I doubt you understand what I am saying.
