In a literal display of burying his head in the sand (or in this case underneath a mountain) and hoping for the best, Beck proposed an idea of hiding away some of the best athletes, minds, and professionals in various fields in his elaborate cave system and letting the rest of the world perish. So while Michael Jordan, Bill Gates, and Rue McClanahan were probably okay, the rest of us were pretty well screwed. That anyone might survive what turned out to be a grossly overestimated doomsday was apparently beyond his comprehension.
"Gentleman, I propose a bold strategy."
When the meteor crashed and killed far less people than he had anticipated, it's a safe bet that Beck had a tough time trying to get the masses he'd abandoned to gruesome deaths to forget that he deemed them completely unworthy of continuing to live.
What He Should Have Done Instead
Hindsight is 20/20, but the fact remains that Beck didn't even really suggest any survival strategies or even seem to be thinking about anything other than saving his own and, presumably, the asses of his many financial backers.
If nothing else, with the knowledge that the meteor was going to hit off of the east coast and the majority of the damage would be done to the eastern seaboard, he could have reminded the people that Manifest Destiny needn't be a passing fad, like acid wash jeans or Tila Tequila. Instead, he could have recommended that maybe it'd be a good idea to flee to the west. Hell, it's not like anyone is using Montana or Wyoming anyway.
Wyoming State Motto: "We're so lonely."
Seeing the aftermath of the meteor crashing into the earth, we now know that if only he'd suggested that long awaited trip to check out Mount Rushmore (on which he'll probably never see his face added) a whole pantsload of American voters could have been saved. And if he'd suggested it in that soothing Morgan Freeman voice of his, we're betting he could have salvaged a few votes in the process.
