Natural selection, among humans anyway, is dead. Oh sure, sometimes an idiot will mercifully take himself out of the genepool by bobbing for apples in an industral blender, but as a rule, all of the smart and/or sane people are carefully culling themselves from the mix while the morons are popping out kids like assembly lines.
Now I'm the furthest thing from an elitist, since you can be poor and certainly be worthy of reproduction or be incredibly wealthy and best serve society by shooting yourself. Still though, it is those people too stupid to figure out how a condom works or that you're not supposed to eat contraceptive jelly that are populating our planet. Them, and those evil guys who don't give a shit and those desperate chicks who'll give it up to anybody are making up the new generation.
There's something inherently unfair about the fact that, for example, the high school drop-out drug-abusing petty-criminal fiancee of my ex-girlfriend-turned-evil-backstabbing-'ho gets to splatter the world with his degenerate seed while my genetics are still firmly locked in my nads (but I'm not bitter).
That's not to say that I'm a genetic marvel. I'm very near sighted and used to be asthmatic, so if I lived a hundred years ago, I'd be dead before I had the chance to score. That's the other problem with things today: people with genetic defects that would have been fatal in the regular world are living and spreading their genes. I'm not going to protest that too loudly, though.
Perhaps the miracles of genetic engineering will save us yet, or maybe it will end up like one of those Twilight Zone episodes where everybody is alike. I guess if all the guys are like me and all the chicks are like Cindy Crawford, that wouldn't be too bad.
