It's not a question of that, it's a question of wholesale exportation of jobs overseas to get 1) cheaper labor 2) avoid government regulation 3) dodge taxes. There's lots of reasons why things cost more to produce in some countries vs. others. Because kids are small, they can get into small areas so why not use them in the manufacturing process for say ships? I can see Korean kids getting into all of those nooks and small areas. That's a niche market isn't it?
It's not like it hasn't all been done before.
I'm not arguing against globalization, far from it. US Consumers have also wrought most of this on themselves because that $19.99 thing from China is a must have item or a new Walmart opened up down the street so everybody has to shop there. Competition is healthy when everybody is playing by the same rules, not when one country dumps products and blocks its markets from US product . Or when it happens in other economic areas.. surprise!.
So, greed is everywhere from the consumer to the companies that export jobs to nations with policies to undermine entire industries. It's time people woke up and started smelling the cat shit otherwise it'll be cat food that you'll be eating when you get too old and can't retire comfortably.
