Anyways, he basically trained his replacement(s) before they laid off a large portion of his machine shop. He trained probably 15 - 20 Chinese over the course of a few years. In the end, as expected, they laid him off. Fast forward 10 years and they had to bring a lot of the tool making back.
Turns out the Chinese either had worse quality control or poorer skill, but they simply couldn't produce at the same level. You only need a few molds for a production line, but each needs to be near perfect. The Chinese couldn't do it. And even when they did / could, the intellectual property was often stolen, so competitors would pop up and customers would get pissed.
You're correct automation is needed. However, so is high quality standards, higher education, higher moral codes / higher pay to keep people honest. The fact is, you can't really find skilled labor elsewhere easily (they want the same as the US wages). That's why the US's number one export is education, and probably why every company still fights over software engineers and really every STEM field.
Unfortunately for manufacturing, the fight is over. When they tried to bring the tool making back there were very few people still doing it. Every single one of my dad's friends (including my dad) had moved on to other jobs. The fact is, all that tribal knowledgewas passed down from master to apprentice was lost. After they laid off the masters, there was/is no one left to really continue.
Personally, I view this as a loss of critical mass and now our skills are likely no better than anywhere else, at least for tool making.
I think this is a warning for every business. Sometimes it's worth paying the price to keep talent. Companies like Google, Apple, et al, know this. Hopefully, that will keep tech and a lot of the other large US companies from losing their way.
