I've been privileged to have spent a little bit of time overseas, travelling, on exchange, working and living. I've hit most of North America and Western Europe, throughout the Caribbean, bits of Asia and a fair swath of the Middle East.

I agree that everybody should spend time overseas. It very rarely is a mind-warping experience, but over time it changes your perspective in ways that are very hard to communicate. That slow process of taking textbook facts and walking around in them and making them real is something that has to be experienced to grok.

I recall my wife, who grew up in South Korea and immigrated to the U.S., but who had never been to any other country, the first time we visited the mainland of Italy. The gargantuan magnitude of ancient Rome simply overwhelmed her. Growing up in a very old culture, and then living for years in a young one, she had built up a kind of healthy hubris that was simply shattered walking through thousand year old remains of something as mundane as a public bath or a stadium or a public square. Things which modern Korea has plenty of, but to see that somebody else had come up with the idea and built an empire full of these things centuries before her culture had even come up with their own written language was thoroughly humbling.

She initially felt it diminished where she came from, but over time she was able to assimilate the experience and finally appreciated it, not as a diminishment of her identity, but as an expansion of it.

All that being said, I disagree with this article:

1 - Marketplace value due to oversupply of college grads in the U.S. vs. undersupply elsewhere: In many of the countries I've visited, the number of highly educated barristas, taxi drivers and other low-end service workers is simply overwhelming. I've met people with dual Master's equivalents who spend their work day standing in a costume at the entrance to a parking garage at a department store bowing to cars coming in. Trust me, getting college grads into jobs where a college degree is needed is typically not a problem in most countries (think supply and demand, if this were even trivially true, those jobs would pay astronomical salaries, but even in highly developed economies like Japan, they don't). Unless you just happen to have some specific skill set, and happen to be fluent in the local language, chances are this entire reason simply won't hold true.

2 - Quality of life: True in some still developing, but otherwise nice countries, absolutely false in the developed areas. Moscow, while still so-so, can easily cost more than NYC to live in; 12 years ago you could live in Seoul for about 1/3rd of life in an urban part of the U.S., today it's about the same, a nice meal in Bangkok might cost you more than in U.S.! Caracas now ranks in the top 10 most expensive cities anywhere, likewise Singapore. Fancy paying $8 for a beer, or $20 for a movie ticket? Welcome to Kinshasa and Port Moresby respectively.

Other modern conveniences might similarly cost much more, how about paying twice the U.S. price for an iPad with no app store support for your country. How about Singapore's insane car ownership tax, how about paying $40,000 for a Honda Civic? And oh yeah, gas will cost you. Let's move to Seoul where you have to put a deposit down on an apartment so large you can't even buy the car in the first place.

Let's not forget lax food safety standards, corrupt police, unbelievable pollution...yes I'd like to live in Beijing where every day outside is like smoking a pack of cigarettes.

Before you know it, the thin veneer of pseudo-quality of life familiarness goes away astonishingly quickly when you're squatting over a hole in dirty train station because the camel foot you ate wasn't cooked enough.

3 - The Jobs aren't coming back. Nonsense, it's a pendulum for some jobs and doesn't matter for others. Do you think all the high-end finance jobs are heading for Urumqi? Or that we're suddenly going to start outsourcing local auto-accident lawyers to Dehradun? If anything, the U.S. is shifting lots of outsource jobs back into the states after realizing that outsourcing development, even at cheapo labor rates, often costs more. If the number of Indians moving into my part of the U.S. for high-end work is any kind of thermometer, the jobs are definitely coming back. A commuter bus I take every once in a while completely defies this logic with a majority of the riders educated and Indian!

As China's standard of living is increasing we're seeing the obvious effects, it's not necessarily going to be cheaper to build stuff in China forever going forward. And obviously, moving to an area like that defies #1 and #2 above due to lousy pay and long hours in a job where you can assemble an insignificant part of a device that'll be bought and used thousands of miles from you.

4 - Yeah, broaden your horizons! I don't disagree, but think of it this way, would a New Yorker, struggling in the tough competitive environment of NYC suddenly move to rural Arkansas because he might get a job more easily? No! Why move to another's country's version of the same? I've often been surprised at the places I'd love to move to (and even at the places I wouldn't). But I've got to get real, no matter how cheap the table wine is in Florence, moving there is not going to give me any kind of jobs benefit whatsoever.

Take an ESL teaching job for a year in another country for the exposure? Cool! But don't think it'll substantially distinguish you in the market or give you any other benefit other than a unique life experience.
