There is a very old saying that I think applies. "There is nothing new under the sun" Reality is that change is a part of the human condition. Every time in the past that the resources have been consolidated they get redistributed through war and conflict. There is no reason to think that technology is going to change this and in fact one of the things that may happen is told as a story in Dune by Brian Herbert and Kevin J. Anderson.

In a far away future mankind has conquered the stars after many wars thinking machines become outlawed. Experimenting with thinking machines is the social taboo of the civilized star nations and will lead to the destruction of anyone audacious enough to go against the prohibition.

What we call civilization is really a cycle of boom and bust. We are a slave dependant society that really has never been civilized. Ethics have never existed for any other reason then to keep the vast majority of people producing so that a very small minority can live in comfort. Robots will vastly more efficiently consolidate the resources which just means the cycle will speed up.

I sencerly hope that I am wrong, but would bet my money on the old saying "There is nothing new under the sun".
