>Many Americans just don't think beyond their own borders.
In Canada, at least, we have a series of regulatory bodies that certify products. Getting your product certified takes salaries, time, and you are charged a fee. For those retailers who are even aware of us, we're a wee country of 30 million so maybe it's just not worth the investment for some companies. (This is why we don't have and can't get Jetboils, for instance.)
Regarding Americans who think that the world begins and ends in the USA, we experience this living in Canada. You can *see* the US border from Vancouver, and yet in many cases I might as well be in istanbul.
I hate to bring up the subject of the 11% of 18-24-year-old Americans who can't find America on a map, but it my experience Americentrism runs rampant down there. 29% can't find the Pacific Ocean, and 15% *can* find Iraq despite having allowed their gov't to spend 0.5 trillion dollars on it. Given those numbers, do you think the average retailer can even imagine what would be involved in exporting a product to a foreign country? There is certification, customs brokerage, international payment methods, and of course the threat of scams. If you still haven't tapped your home market of 300 million relatively moneyed people who speak your language, why bother messing around with what you call "foreigners?" I guess.
I rode a bus from Seattle to Vancouver once, sitting next to a pretty American girl who was *moving* to Manitoba. Imagine her surprise when I explained to her that we have different money in Canada! She then started a string of other questions: do we have Christmas, do we have a President, and is it colder in Manitoba than in Northern California where she was coming from.
Secretly, though, many Canadians don't mind this situation. If more people down south looked outside of their borders, they'd realize that we have all the same hiking, fishing, and hunting -- except that it's more remote, more pristine and unspoiled, with 1%-10% of the usage in many cases. And without the fees/regulation/park rangers/having to poo in a bag and carry it with you.
Shhhhh! Don't tell anyone please :-)
