The Camrys (including the hybrids) and Corollas which Toyota sells in the U.S. are actually made in the U.S. That means the consruction and sale of these models helps the U.S. jobs market.
It took me about 10 seconds of research on the internet to find that out. Perhaps the writer of the article should have done the same.
Writer of the article knows that. What he also knows, and what you are overlooking is the fact that a huge part of the money goes to Japan and Japanese workers because the companies are owned by the Japanese. They are assembled here, many of the parts are made in Japan and, as I have said, a large part of the profits goes to Japan.
However, some US workers benefit and the UAW gets screwed. The whole idea of the cash for clunkers program was to enrich US car companies and the UAW, it was just another payback for them, the fact that they are getting screwed from their own brilliant plan is the whole point of the article.
