That's a very funny observation of you, but let's digress-
When you go to have a product made in China, and lets say you approach a design manufacturer there with your proposed part, they'll sit down with you and literally pull up giant lists of all the companies in like- Shenzhen, and say "okay, this company makes the rubber buttons that are kinda similar to what you want, this company makes the aluminum housings, this company makes the tempered glass, this company makes the ABS plastic clasps, this company makes the rubber... etc... etc... etc...
Basically what they do is look you dead in the eye and ask you to alter your product so that they can sub-contract out to about 50+ companies that churn out a fairly uniform part, that they can then cobble together into your desired product.
Sure, you can custom order things to look different, but that's really expensive, and usually one of those Shenzhen/Qingdao/Shanghai manufacturing hub companies will only have tooling or dies to make like one, or a handful of variations that you can order.
So you end up in this scenario where finished products LOOK like they all came out of the same factory in China, but in fact they all came from like 1,000 different factories, that just all pump uniform parts by the metric ton.
Americans aren't really used to this style of manufacturing, because it used to be that most things were made in house, and hand fit, or a company would actually demand that you order something in excess of X-thousand, or x-million parts to justify them buying or making all the tooling to make your highly specific special snowflake part.

Those contracts aren't as juicy as they sound btw, there's nothing worse than someone contracting your little no name shop for a special snowflake one-off, it's incredibly expensive for YOUR shop to make, you usually lose profit on that.
