In reality, "best if things are produced where they can be made most effectively" is usually a roundabout way to say "best if things are produced by the labor whom we can get away with paying as little as possible". Hence, outsourcing to countries where you can get away with smaller wages because the overall living standard is lower there and/or because the labor laws are non-existent or not enforced. But it's the same exact thing, just on a larger scale - you're still inherently relying on some people somewhere having a significantly lower quality of life than us to be able to exploit them like that.
