You're arguing that American manufacturing is healthy because of Boeing?
We're not the largest in absolute output, but we are literally the best manufacturer in the world, and we are the 2nd largest.
We manufacture lots of stuff, often the most state of the art and difficult things to manufacture. We're very good at it.
And we've sat around close to full employment for so long, the only way to convert more of the economy to manufacturing is to either import workers, cannibalize other sectors of the economy, or automate even more.
Yes, a larger share of the economy is services, but is there some objective optimal ratio of services to manufacturing we should be shooting for? If so, what is it? No one ever says.
Sending emails from an ergonomic chair for eight* hours a day and having to be civil to female coworkers and polite to your boss inherently degrades the male spirit in a way that permanently damaging and poisoning your body with 12-hour factory shifts with a foreman yelling at you doesn't. This is so self-evident and obvious that nobody even bothers to state it, it's just an assumed undercurrent in discussions of "bullshit jobs" etc.
The fact that leadership is focused on extracting profits out of the enterprise is also not a show of strength. It's a demonstration that they're trying to drain whatever value is left in it.
This is pretty much true of any of the American "greats:" Boeing, Intel, GE, GM, Corning. They're producing (or have recently been producing) great profits because they're eating their own seed corn. Nobody expects them to still be the businesses they currently are in another few decades.
