That's just a bunch of strawmen and a made up assertion: "people complaining about the decline of society are contributing more to it than anyone else" - oh yeah? Nietzsche, Erich Fromm and *thousands* others will still be read, and still have something worthwhile to say, when the last mirror of xkcd has blinked out of existence. Pah.
And you know, when I thought of "career" and "frozen eggs" I had to think of that particular bit in the opening of Idiocracy. If you think I was trying to claim freezing eggs will lead to the decline of human intelligence you're an idiot. I don't even think IQ necessarily has anything to do with how wise or how idiotic people are. It's like a really fast car, you can still drive in circles with it. Just really fast, yay.
