> but maybe international outsourcing is the way to go in some areas

Seems like a lot of people forget there was a fairly massive push for this back in the early to mid aughts (for example, google "tech outsourcing 2004", as iirc 2004 was around the peak of the mania) and it generally didn't work out so great, with most companies who tried it pulling back away from it a year or two later.

Maybe it'll work better now, but I haven't seen evidence that much has changed that would modify the outcomes.
