BTW, for those wondering where a lot of these manufacturing jobs are coming from when it doesn't seem obvious from looking at your city, most big cities have a lot of "hidden" manufacturing tucked away in some of the most unlikely places. Much of it, I might add, is probably not what you'd think of as "manufacturing." For example, many years ago I did a temp job at a company in Pioneer Square in Seattle, 2nd floor of one of the old buildings. They made some sort of health formula (I forget exactly what it was, it was stuff that looked like Metamucil or some sort of protein powder but it did ... I forget what). Anyway, they had some machinery in this one room that poured the different ingredients together in various combinations into the containers, then mixed it up and sealed the packaging. Technically speaking, that's manufacturing (food processing, in this case). It was taking some raw materials and putting them together into a finished product.
I suspect a lot of the "manufacturing" in the jobs listed above is stuff like that, in addition to the more traditional kinds of manufacturing.
Another thing I learned several years ago, last time I bought a mattress ... All mattresses are made locally. For various reasons it's not worth it to ship mattresses long distance. So, every metro area has a bunch of mattress factories. The last one I bought in Seattle was made
here, and there is another one nearby
here. Close to my new locale there is one
here I pass on the way to and from work every day.
