Well that is what one would expect.
No one off shores to China to get a higher quality part , for now.
In 15 years or so the top end ones will be made in China and the bottom end will be made in the USA, but like Korea, & Japan previously it will take a little time before their products are 200% better than the product they were copying.
Been around for a while seen this happen 1/2 dozen or more times.
