That reminds me of something I heard recently about commercial fishing in the Atlantic, IIRC. It was cheaper to catch the fish in the Atlantic, ship them to China to have them fileted, and ship them back to Europe, than to do it all in Europe.
It never has made sense to me, how crossing the ocean twice in a container ship on top of labor can be cheaper than processing at or near the source. Beyond that, quality and freshness has to suffer greatly. When domestic capacity to handle this is gone or greatly diminished due to loss of business, there won't be any other option. Seems like a bad idea to me.
