It's cheap, yes. I can indeed buy 1,000 of something more locally or from other than China.
But when it comes to scale, needing vast shipments, then they are the ones who can actually ship it and do it reliably. It just also happens to be cheaper, too, which is more of a convenience or cherry on top, than the actual attractive part: vast scale.
Three or four decades of proven ability to deliver, trusted relationships.
Even despite all the political noise.
I don't think trust has much to do with it
They're reliable, but would you really trust them?
I think there's a bit of nuance there to differentiate the 2 though.
Maybe I'm jaded from working with overseas factories though in ways others wouldn't be.
So not really a good comparison
When you have the design it takes away alot of the need to even reverse engineer in the first place
Trust implies shared values/worldview and past experiences where outcomes match expectations. Also respect.
Trust is not possible when there are regularly incongruous outcomes, or where definition of respect / values are just aren't aligned.
Do you think your counterparts overseas believe themselves to be as trustable as you are, and it's just a cultural rift? Or is that too charitable?
Now that hasn't been the case for more than a decade. The cheap labor is in SE Asia and South America.
What China has is decades of process improvement, factories, infrastructure, experience, and a willingness to work. They haven't been the cheapest, by far, for a long while.
