That's really just not true. The Japanese vehicles made in the USA are not only assembled by thousands of American workers, but most of the parts are also made here. In fact, many of the parts are actually made by American companies. For example, if you recall the recent uproar in the media about Toyota gas pedals? Those pedals were made by CTS, who also made pedals and various other parts for Ford and other manufacturers.
If you work in the service department and have to replace a part on a vehicle you must usually put the VIN number in to find out if you need the Japanese or American parts because in many cases they are not the same fit and you must make sure you order the right part. So if you have a Honda Accord that was built in the USA and order the Japanese part, it will not fit. There are slight differences.
I will agree that the profits do tend to go overseas back to the main company, though. But it is still better than buying a foreign built car because at least the USA built cars do employ a lot of American workers and contribute to our economy.
Don't believe me? Then, prove it to yourself. Choose one of the Asian branded vehicles that are claimed to be made in America. Any of them, you choose. Then, choose ten parts on the car. Any ten, you choose. Go to the dealer and ask for those parts. Get a good mixture. Try a valve cover gasket, wheel bearings, tail light assy, air filter, etc. Then look at the packaging. See how many, if any, were made here. I'll bet all were made in Asia. Then, choose another ten and look at those. You'll soon see that there are virtually no parts made in America. The Japanese marketing departments fooled you.
They do that by assemblies. They ship engine parts, for example, from Japan to an assembly plant here. They then assemble the engine, ship it to the main assembly plant, and call it "Made in America" because it was assembled here. That way, they can fool the feds, too.
If you think that the assembly line workers make up for that, then check this out.
