A speculation about outsourcing -

8. Um, I was a product designer, moldmaker.

First off, plastic is not always lower quality. Second, planned obsolescence, is built in, for a reason. And since you finely engineer in failure, that makes quality control MORE important.

As an example, a fellow moldmaker was told by a boss, to grind down the core, on a trashcan mold. It had significant weld aplied to it. He asked, what was wrong with the product? Boss said, nothing, they just wouldnt wear out. So, thin the cross section on the bottom.

to add to this, they print on any device, no user serviceable parts.

Also, when you move the plant to far away, packaging, shipping and wait time, makes customer service, and warranty moot.

Breakage, is a term that applies. In rebates, it is the bother. Or time limits etc.
