Is absolute equality possible?

Swami Vivekananda says :

Absolute equality, that which means a perfect balance of all the struggling forces in all the planes, can never be in this world. Before you attain that state, the world will have become quite unfit for any kind of life, and no one will be there. We find, therefore, that all these ideas of the millennium and of absolute equality are not only impossible but also that, if we try to carry them out, they will lead us surely enough to the day of destruction. What makes the difference between man and man? It is largely the difference in the brain. Nowadays no one but a lunatic will say that we are all born with the same brain power. We come into the world with unequal endowments; we come as greater men or as lesser men, and there is no getting away from that pre-natally determined condition. The American Indians were in this country for thousands of years, and a few handfuls of your ancestors came to their land. What difference they have caused in the appearance of the country! Why did not the Indians make improvements and build cities, if all were equal? With your ancestors a different sort of brain power came into the land, different bundles of past impressions came, and they worked out and manifested themselves. Absolute non-differentiation is death. So long as this world lasts, differentiation there will and must be, and the millennium of perfect equality will come only when a cycle of creation comes to its end. Before that, equality cannot be. Yet this idea of realising the millennium is a great motive power. Just as inequality is necessary for creation itself, so the struggle to limit it is also necessary. If there were no struggle to become free and get back to God, there would be no creation either. It is the difference between these two forces that determines the nature of the motives of men. There will always be these motives to work, some tending towards bondage and others towards freedom.(I, 114-15)
