I've contributed in my small way to the GNP of many different countries.
Graphic desingers in US, UK, Russia. Programmers from US, Canada, Israel. Had employees from Australia in the past. And it's not always the money but also how good are they? If they can do the job effectively and we can communicate easily, doesn't matter to me where they are. If I save some coin in the process, that's a bonus.
And It swings both ways, if they suck, being in the US doesn't help them either!
