Globalization is a very broad, encompassing term, sometimes driven by historical and technological factors. For all intents and purposes, I'll be focusing on the neo-liberal version espoused by many Western governments, which has been a primary precipitant in the ongoing financial breakdown crisis.
Effectively, this form of globalization is just another variant of plunder, pillage and mass impoverishment, with the projection of military power being the means that it is carried out, and large scale capital accumulation by a small oligarchy being the primary outcome. They use political destabilization, separatist movements (divide and conquer), and economic coercion to force their interests on other nations in the "periphery". To them, periods of civil unrest is when the greatest profits can be made, as those are the points when assets can be effectively stolen from nations.
Our foreign policy is defined by the need to secure markets and raw materials at a steep discount. The "War on Terror", which our leaders claim will last for another 50 years, is nothing but a glorified resource war targeting a wide swath of Africa, Asia and the Middle East. But today, the mechanisms by which global profits are enhanced have gone far beyond the exploitation of markets, resources and labor; they embrace entire nations, peoples and the public treasuries, not only of regions of Africa, Asia and Latin America, as it usually has, but include the so-called "debtor countries of Europe", Ireland, Greece, Spain, Portugal and Italy, among others. Speculative capital has no nationality, it attacks areas that are weakest. It's basically a legalized form of piracy.
The World Bank, the IMF and other agencies closely connected with the large money center banks in New York and London facilitate the process. Typically, the process starts with hot speculative capital flows entering a nation that has just deregulated their financial markets and pumping up their asset values. Once these markets reach a certain price point, capital pulls out and causes these economies to crater, leaving in its wake huge amounts of debt that are nearly impossible to pay off and a good deal of political instability.
What happens next is that a begging foreign minister goes to the IMF or even the large banks, asking to restructure their debt. Every time, they are forced into accepting structural adjustment, which is nothing but the effective asset-stripping of entire nations. The first step in that process is the privatization of state controlled assets. Rather than object to the sell-offs of state industries, many of the local politicians happily flog their electricity and water companies to international conglomerates, expecting to shave off millions of dollars in the final terms of the deal.
After privatization, the second step is additional capital market liberalization, in addition to similar measures that were implemented earlier. In theory this allows investment capital to flow in and out. Unfortunately, as happened over the past several years in places like Indonesia, Mexico, Argentina, and most recently Southern Europe, Northern Africa and the Middle East, the money often simply flows out. This is known as the "hot money" cycle. Cash comes in for speculation in real estate and currency, then flees at the first whiff of trouble. A nation's reserves can drain in days. And when that happens, to seduce speculators into returning a nation's own capital funds, the IMF demands these nations raise interest rates to 30%, 50% and even up to 80% in more extreme cases. The result is predicable: higher interest rates demolish property values, destroys industrial production and drain national treasuries.
At that point, the IMF and the international banking authorities go on to the third step, which involves "market-based pricing", which is basically a euphemism for raising prices on food, water and cooking gas. The result is always the same: food riots always ensue. That is what is currently happening in Egypt as we speak, as the Muslim Brotherhood backed government there has embraced IMF conditionality. What happens is that when a nation is down and out for the count, the banks squeeze the last drop of blood out of them. They turn up the heat until, finally, the whole cauldron blows up. The result is fire sale prices for all kinds of assets, from mineral concessions, to industrial plants and production.
This is what many, including last year's GOP presidential nominee, Mitt Romney, refers to as "creative destruction." But it's nothing but thievery and an attack on sovereign nations. Nations that are not compliant in these objectives typically faces political and economic sanctions, and in more extreme cases, US/NATO military intervention is possible, under some sort of secondary pretext oftentimes.
