> The net result is that US manufacturing output in real dollars has increased 4x, in the past 70 years.

All of that manufacturing growth is semiconductors, and most of that measured semiconductors growth is simply Moore's law. I don't think anybody would say that the US is worse at making transistors today than it was in 1970, but that's table stakes; everybody is better at making transistors than they were in 1970. Automotive manufacturing has also done well (in part thanks to trade barriers). When it comes to everything else -- vacuum cleaners, fans, washing machines -- that manufacturing output is not doing so well.
