When you say "has largely left", that implies that we no longer have companies doing the work, that we've lost the capability to do the work. That doesn't seem to be the case, at least not based on these figures.
If we're producing less steel than we used to, but we're still producing some, then we still have the capability to expand. Production is down and if it continues we'll eventually lose the ability to produce our own steel, but we're not there yet.
For consumer electronics, I disagree that "everyone would likely agree that consumer electronics manufacturing has largely left the US", especially if our production of consumer electronics is up. (Is it rising as well?) We may not be the leader anymore, but that's very different from "largely left".
I don't believe that everything is fine with US manufacturing; I think it's a problem that there are many things we still need which we don't make anymore. But there are many things that we do make, even when other countries make them too, so it's not all doom and gloom.

I think this is wishful thinking. Well we've shed ~75% of jobs from the steel industry in the past 5 decades. We don't produce enough steel to meet our own needs. In fact we are the top importer.
Most of the integrated steel mills are shuttered, down to 11 from something like 50. There used to be 9 in Cleveland alone. Now there is 1.
We have some companies doing the work, but we have fewer, and they're doing less of it.
> If we're producing less steel than we used to, but we're still producing some, then we still have the capability to expand.
This is a meaningless statement. If our production was zero, we'd still have the capacity to expand. The reality though is that we are not expanding production. It's contracting while the industry in general is booming.
If US car manufacturing were down 30% since 1970 while worldwide sales were up 200%, I think everyone would agree that our automotive industry was floundering. In fact the numbers for car manufacturing aren't nearly that bad and most everyone still agrees that the U.S. car industry is in trouble.
> Production is down and if it continues we'll eventually lose the ability to produce our own steel, but we're not there yet.
Of course we're not there. But we don't have to hit zero before we're in trouble, nor do we have to hit zero before we're effectively unable to meet our own needs. At this point we already (net) import something like 25% of the steel that we need.

I made up an example. I suspect that it is up since Woz was putting together Apple Is in a garage. When the numbers are that small, it's not hard for them to grow. At the same time, we basically have no domestic electronics manufacturing industry. The vast, vast majority of that happens in Asia. Even if our overall numbers are actually up, our manufacturing doesn't exist in a vacuum. When our own consumption is virtually completely outsourced, our industry has utterly failed to meet the demand and it's fair to say that the industry has effectively left.
It seems unreasonable to me to look at total output in isolation as if no other factors are relevant. While we might produce 70% of the steel we used to, we produce far less virgin steel than we used to. And we cover far less of our own needs than we used to. And we produce far less of the world's supply than we used to. And we employ far fewer people. And we have far fewer steel mills.

I don't think it's all doom and gloom, but the steel industry is clearly largely outside the US now.
If we're producing less steel than we used to, but we're still producing some, then we still have the capability to expand. Production is down and if it continues we'll eventually lose the ability to produce our own steel, but we're not there yet.
