in terms of military and political power... The combination is quite scary.
Speaking of IMF, global economic crisis, and role of the financial oligarchy and corruption in the US...
here's a pretty amazing read (by a pretty unlikely source), I read the whole thing last weekend and highly recommend it, lots of insights there:
The Quiet Coup:
http://www.theatlantic.com/magazine/archive/2009/05/the-quiet-coup/7364/The crash has laid bare many unpleasant truths about the United States. One of the most alarming, says a former chief economist of the International Monetary Fund, is that the finance industry has effectively captured our government—a state of affairs that more typically describes emerging markets, and is at the center of many emerging-market crises. If the IMF’s staff could speak freely about the U.S., it would tell us what it tells all countries in this situation: recovery will fail unless we break the financial oligarchy that is blocking essential reform. And if we are to prevent a true depression, we’re running out of time.
In its depth and suddenness, the U.S. economic and financial crisis is shockingly reminiscent of moments we have recently seen in emerging markets (and only in emerging markets): South Korea (1997), Malaysia (1998), Russia and Argentina (time and again). ... Just as in emerging-market crises, the weakness in the banking system has quickly rippled out into the rest of the economy, causing a severe economic contraction and hardship for millions of people.
But there’s a deeper and more disturbing similarity: elite business interests—financiers, in the case of the U.S.—played a central role in creating the crisis, making ever-larger gambles, with the implicit backing of the government, until the inevitable collapse. More alarming, they are now using their influence to prevent precisely the sorts of reforms that are needed, and fast, to pull the economy out of its nosedive. The government seems helpless, or unwilling, to act against them.
Basically, he says that the US is essentially a "banana republic", like you said, in terms of corruption and financial oligarchy, but it has unprecedented military and political power and control of world economy. A very dangerous situation...
