There are a bunch of upsides here. Industrialisation increases standard of living compared to an agrarian economy. A service economy, where services mean things like industrial engineering and product marketing, increases standard of living even further.

I get that tool and die is going to be in demand again one day, but that's not an overall downside. For that to happen, every country which could be outsourced to will be too wealthy and have a service economy, and they'll have to use their wealth to hire the last remaining tool and die makers as instructors. Compared to the upsides of nobody being a subsistence farmer or sweatshop worker anymore, and of most people living in advanced economies, that downside is small.
