If economic slumps can be rated by how many Starbucks a country has, then Korea is really screwed:

In the same spirit, I propose the Starbucks theory of international economics. The higher the concentration of expensive, nautically themed, faux-Italian-branded Frappuccino joints in a country’s financial capital, the more likely the country is to have suffered catastrophic financial losses. (…)

Like American financial capitalism, Starbucks, fueled by the capital markets, took a great idea too far (quality coffee for Starbucks, securitization for Wall Street) and diluted the experience unnecessarily (subprime food such as egg-and-sausage sandwiches for Starbucks, subprime loans for Wall Street). Like so many sadder-but-wiser Miami condo developers, Starbucks operated on a “build it and they will come” philosophy. Like many of the humiliated Wall Street firms, the coffee company let algorithms and number-crunching get the better of sound judgment: If the waiting time at one Starbucks was over a certain number of minutes, Starbucks reasoned that an opposite corner could sustain a new outlet. Like the housing market, Starbucks peaked in the spring of 2006 and has since fallen precipitously.  [Daniel Gross - Slate]

So how many Starbucks does South Korea have?  Well many more then most countries:

What does this have to do with the price of coffee? Well, when you start poking around Starbucks’ international store locator, some interesting patterns emerge. At first blush, there’s a pretty close correlation between a country having a significant Starbucks presence, especially in its financial capital, and major financial cock-ups, from Australia (big blowups in finance, hedge funds, and asset management companies; 23 stores) to the United Kingdom (nationalization of its largest banks). In many ways, London in recent years has been a more concentrated version of New York—the wellspring of many toxic innovations, a hedge-fund haven. It sports 256 Starbucks. In Spain, which is now grappling with the bursting of a speculative coastal real-estate bubble (sound familiar?), the financial capital, Madrid, has 48 outlets. In crazy Dubai, 48 Starbucks outlets serve a population of 1.4 million. And so on: South Korea, which is bailing outs its banks big time, has 253; Paris, the locus of several embarrassing debacles, has 35.

Well I guess one way to look at this theory is that North Korea should be a good place to invest since they have no Starbucks.
