A contributing factor in all of this is that US manufacturers have spent the better part of the last 30 years turning their engineering departments into glorified parts replacers. A complaint I have heard from nearly every electrical/electronics engineer that I've known is that "We don't design things anymore. Now we just spend most of our time trying to find replacements for chips that we can no longer get."
From what I can tell, from my very limited perspective, there has been a significant lack of investment in engineering capabilities and a resulting lack of innovation for a long time. As usual, short term thinking is expensive in the long run. We're only just beginning to find out how expensive.
