I’m intimately familiar with companies that build tooling for other companies, most of which are Automation Alley companies (despite the Wikipedia article, there are now associated areas in Michigan that seem to be able to claim such; every time I enter St. Clair County there’s a sign that indicates “We’re an Automation Alley County” or something to that effect.).
I’ll preface my next by saying, buy whatever car or truck you like; I hope you like American brands but if not, that’s your choice. Now I’ll go on to illustrate why a Hyundai plant that employs 2000 US workers isn’t the same as a, say “AMC” plant that employs 2000 US workers.
It’s the organizations that build the tools. What’s it take to make a car? Well, sheetmetal, paint, engines, electronics, and plastics. There’s a building that stamps sheetmetal, another that welds it together, another that paints it, and another that puts in the engines, puts on the tires, and finalizes the assembly. There are also many, many plants that supply all of those materials (usually suppliers; not done in-house). Of course in the spirit of the OP, you need to someone to build all of the tooling that inhabits these factories. These are the guys in Automation Alley. One company builds logical controls. Another robots. Another presses. Another weld guns. Another nut delivery tools. Another nut tightening tools. Another conveyors. Another electric motors. So on and so on. Then there are integration suppliers that actually put all of this stuff together into a coherent system. Of course all of these suppliers need to purchase service vehicles, computers, tools, raw materials, and so on and so on in order to work. On the employees’ off hours they need food, houses, clothes.
So far, Hyundai and AMC have all of the same requirements. However in the course of the AMC plant, all of these billions of dollars were spent in the United States, and stayed in the United States. All of this work and tooling in the case of Hyundai goes back to Korea and China. Sure, then end result is that AMC and Hyundai both employ and provide jobs to 2000 Americans in the assembly line, but that’s only a tiny, itty bitty fraction of the auto industry as a whole. The real big bucks are the things you normally just don’t think about. There’s literally no industry (industrial industry, that is) more important in the United States. It’s not because of 2000 line workers, but because of everything else prior to that point.
This certainly isn’t meant to try to persuade anyone to buy an AMC; hijacking aside, it seems like an opportune time to demonstrate how important companies are that build machinery for other companies.
