Where something is from doesn't matter so much as how carefully it was constructed. I have several high quality basses that were made in Indonesia. On the other hand, I'm sure there are some lower quality ones made there as well - that's pretty much true everywhere. No country really has a lock on either craftspeople or CNC machines.
This works if you have time to got through every brand and model, which we don't.
Country or origin is akin to a brand - MIJ or MIA is simply a quality filter for those people (most people) who haven't time to trawl through all basses.
Country matters is the same way the name on the headstock matters.
