I think you are somewhat understating the involvement of the design portion of the manufacturing process. I do wish the economic realities would support and encourage US manufacturing at affordable pricing for more products. But even with US made products, components, even major components lik frames, being manufactured by contracted associates rather than the parent company is common. I spent 29 years working for a company that built significant airplane parts and assemblies for the companies that had their name on the final product. I never doubted that the planes were the product of the company that sold them.
