I wouldn't be too surprised if there weren't a bunch of Republican/Conservatives thinking along these lines (even if they haven't thought it out--which is common for them)...
"Conservative Solution"? akin to Hitler's Final Solution... they're hoping for a world war. That would lead to the destruction of the rest of the world (who needs 6,574,214,228 people anyway?), including their "productive" capacity. Obviously they would want to leave some people in the rest of the world--and people capable of some modest productive/economic capacity--but only such that they would want, and be able to pay for, our leadership, managment, guidance, and products. If such a war involved the middle east, maybe, just maybe, we could lay claim to it as spoils of war. If the war reduced China sufficiently, perhaps then we could just claim that "all bets are off" with respect to the vast amount of national debt they hold. Just declare a new currency and *poof*, the rest of the world is screwed--and so long as there's a world war...
Of course, to do such a thing, the U.S. would have to invest hundreds or thousands of billions of dollars in it's military machine--including the development of a
missile defense shield (after all, there are indeed other countries with nuclear weapons and the expertise to send them here). Indeed, to do such a thing, a U.S. government would have to have extraordinary powers over it's own populace--who might just include a bunch of pansies who would think that such a plan is pure insanity. To enable such a thing, a government would have to be able to listen to people's phone calls, search their homes, lock them away, identify all citizens, make the entire economy and monetary system operate by electronic means (no currency for exchange of goods), read their mail, etc... Certainly that's not anything good citizens wouldn't give up in exchange for safety from the gigantic, ubiquitous, ever-present and deadly threat of "terrorism" (al-qaeda).
It should be understood that to the ultra-wealthy, saturated in power, elites, chaos itself represents the greatest opportunity for vast increases in their power and wealth--and most of the risk will be delegated to the regular population...
Okay, taking off the Republican/Conservative fringe thinking hat (as well as the tin-foil liner)... one wonders if the world isn't headed for real problems.
Vast and rapidly growing population with limited resources... (rut-row)
Environmental destruction including Rapid Global Climate Change... (uh-oh)
Potential development and rapid global spread of a deadly pandemic... (ooo-eee)
In any case, things are going to get worse before they get better--and that's going to affect any country that's already used to a high-standard of living (and hurt the ones who can't adjust/adapt for whatver reason, whether it's because the people and their leaders are convinced of their own exceptionalism or rigid adherence to traditions in policies, government and society...) more than one that's used to having much less. Indeed just as heat spreads to areas that are cooler, economic prosperity, to some extent, in a free trade world will flow from an area of density to any other area that's ripe and capable.
Seems that for most folks, bracing for the hard times wouldn't be an outrageous or unwise thing to do. Not an easy thing; even knowing how to brace oneself isn't easy (or even possible in many cases). This would be the time to turn to one's deity and plead, assuming one has one. Meanwhile, getting a more populist, Democratic government in place would best serve the majority here.
