Well, it’s hard to say (for me anyway). I’m not an “expert” in the auto industry, for example. The answer likely vary from “field” to field. But...
Consider auto production. Out of all the major US manufacturers (including producers the size of, say, Subaru), is there so much as one car model that uses less than 100 essential components dependent in some way or another on China? I don’t “know” the answer, but I have a very strong “suspicion”.
Manufacturing is toast until this is over.
At this point I’m worried about ‘trivial’ stuff. Like whether Kroger (and walmart and target and king soopers and etc) has enough oil filters (and air filters and belts and what not) set aside for their fleet to keep it running close to normal...if we can’t get any more for several months.
A lot of the electronics are made in China and pretty much all aftermarket parts are too which is worse. Even the good old brand names have everything made in China now. Raybestos, Wagner, SKF, National etc.
Looks like China supply won’t be so important anyway as it spreads to other nations.
