Societal Decline
I enjoyed the Mike Judge movie Idiocracy, so long as I could suppress the gag reflex — it’s funny, but gross.
But Randall Munroe’s webcomic xkcd makes an excellent point:
More harm has been done by people panicked over societal decline than societal decline ever did.
By George, he’s got something there. You can click the image to see the complete comic.
Those who aren’t already familiar with xkcd might be startled by the crude stick-figure drawings, or by the crude language sometimes present in the comics. I think those things are simply evidence of society’s decline and inevitable collapse, but I could be wrong.
