Re: Scarcity of resource
Time is "free" provided your planning is good enough, so taking a month to deliver goods isn't usually a problem - at least not for bulk industrial stuff once you have built up a stock in country (it's just a question of pipelining delivery so there is always a "big enough" stock in country until the next boat arrives). Less true for smaller orders, of course.
Duties sure - that why I said border tariffs - but on the whole they are reducing over time world-wide as most countries realise that on the whole trade goes up with less tariffs in place.

There are plenty of multinationals around who prove it works, and globalization doesn't mean I necessarily need my company to do all the out-of-country work. I don't need to have an overseas branch to benefit from overseas labour - I just need to buy materials or finished components from someone who does (directly, or via an importer).
