Khrushchev pounded a shoe on a table and shouted "We will bury you!". Khrushchev was, of course, utterly wrong -- his Soviet Union got buried instead, in part because of decisions Khrushchev made which plagued the nation for the remainder of its existence.
The thing is, global capitalism, sans any existential threat forcing it to behave intelligently, appears to be in a race to the bottom right now. Note that none of this is happening because of a lack of resources -- yes, oil is a constraint, but not one we're running up against right now. Instead, it's because without any need for intelligence, our capitalist overlords have resorted to cave-man economics instead... "ugh! Me Ogg! Money good! Ogg keep money instead of investing in workers and schools and infrastructure! Ogg hit workers on head with club! Ugh!".
The problem is that cave-man economics does not work. We have another name for cave-man economics: banana republic economics. Banana republics are poor -- often ridiculously poor given the natural wealth. By preventing their people from becoming educated, by refusing to invest in infrastructure, by hoarding what little wealth exists in the country into their own greedy hands, the ruling elite in banana republics stay on top of the heap -- for a price. And that price is this: No matter how filthy rich they are by comparison to the rest of their people, they still live in a third world hellhole. They can't go on vacation inside their own country because every possible place people can grub food is being grubbed and every possible pollutant is being emitted by what little industrial infrastructure exists, turning the whole nation into a desolate wasteland of poisoned landscapes, corporate plantations and scorched earth. And all it takes to overthrow them is a single brigade of soldiers from any modern army complete with supporting attack helicopters, fighter-bombers, etc., because as rich as they are, they still cannot afford sufficient mercenaries to hold off real troops (and their own people certainly aren't going to fight to defend them).
In short, cave-man economics is a recipe to poverty and economic failure. But that's the predominant economic theory in the world today. Which means that capitalism is well on its way to eating itself up.
The problem.... the problem, though, is that capitalism, when properly regulated, is also the best mechanism for matching supply and demand that has ever been devised. What happens when capitalism collapses? Nothing good. Nothing good. But as long as cave-man economics is the general rule amongst our ruling elites, I have a sad feeling we're going to find out the hard way.
