Very interesting piece. honestly, I don't think those at the top are goaded only by greed (which is, in itself, stupid), but by the fact that someone has to lead this world, by an idea that what they are doing is good.

And while I agree, in part, with what you are saying, I can't help but think that there is something wrong with the idea that if people could be enhanced to be smarter, they'd choose that. Society, for the most part, is made up by people who choose ignorance, or at the very least, are self-indulgent about the fact that they are willfully dumbing down.
TO put it in another way, this isn't really a society who strives for more intelligence and to better itself constantly. Quite the opposite, actually.
