This is all my own interpretation, but it’s a bootstrapping problem. Feynman complained about a consulting gig he took to try to bootstrap STEM programs in South America. You need mentors to make more mentors. If you can’t send people off to train or coax people in, you’re left with whoever can intuit things on their own and explain them to others. That pair of skills is exceptionally rare.
If you are the first factory in an area, nobody knows what to do. So you make simple stuff with high tolerances as you build a base of skilled labor. and a customer base.
Then you ratchet up, and ratchet up, and get nicer customers and more cash and contacts and make products that require more and more sophisticated processes.
If you’re lucky, you make middle to high end stuff that few other people can before the exchange rate completely fucks you vs the next up and comer.
