The people making the decision to offshore to China are not the people who will be doing QA/QC, and they’re definitely not the people who get their hands dirty prior to offshoring. The people who make that decision are trying to cut labor and thus product costs to make their quarterly bonus bigger. They likely won’t be around long enough to even hear about the increase in defective products and if electronic, the corners cut at the Chinese factories on materials.
I worked at a company that had electrical devices manufactured in China and was very displeased when one of the factories offered to whip up any safety certifications we needed with no actual testing. Thankfully the owners quit doing business with that factory after that. Another factory owner collected meal receipts from visitors so they could cheat on their taxes. Anybody openly trying to cheat on their taxes isn’t fooling me with confidence that they’re by the book when it comes to other aspects of their life.
This is literally Russia’s current plan for Siberia. They want access to the vast mineral deposits under the permafrost, and if they wait, getting at those minerals gets a lot easier.
