Let me try to make some optimistic spins?
- Intel is hopefully turning their foundry business around. I think this will be a slow (1-2 decades?) process but will pay results.
- Tesla and SpaceX are actually really positive spins, though I agree Tesla isn't completely isolated from the rest of the eletronics world. It's what we've got and it's not half bad. SpaceX in particular I is world-class at this point and hopefully will continue to get better
- Toyota makes more cars in the US than not. Worst case, these are still functioning production lines staffed by good workers, that talent and working knowledge (hopefully) doesn't just disappear
- A lot of your examples are lower down the value chain, for instance Intel doesn't produce commodity RAM since they famously got out of that game in the 80s(?) to focus on the higher margin CPU business. Maybe this is good?
Ultimately though, I agree that working in ads or finance is largely flat or negative sum to society (as someone who has or is in both). It's worse than that, too. People actively look down on manufacturing, as somehow less exciting and less complex than finance.
