I don't see why the elite should not get together and hatch a plan to eradicate/euthanize most of the lesser population and save this planet for themselves. You are smart enough to pull it off against billions of idiots and human garbage that are not much of a loss by not passing on their genetic material anyways. With more mechanization and robotics, there will be less need for the annoying pollution of lower human labor. Why wouldn't you want the world for yourselves? Seriously, most people are not worth saving physically. Technically, isn't this all a win-win for the planet and for a better society as in to have a more intelligent genetic pool of humans instead of a majority of the unwashed and idiotic masses with the upper tier (intelligentsia, not just money/success) as the minority ? When I say this, I am not excluding myself from the majority either. I just wonder if the upper tier just tolerate the masses because they need them for labor or because they actually believe anything deserves to live, breathe and reproduce. Once they are not needed, why don't you just take over the planet and be rid of the less desirables?
