IIRC the Camry is 85% American build. Build in the Southern States, with wages going to southern workers, who go and spend the money in America. Will they buy American jalopies? Why would they? Its not a smart financial decision. Neither is it a smart practical decision... American cars have to be serviced more often due to poor engineering and assembly.
I just bought my second car assembled in Japan. Is it bad for the American economy? Yes. Is it good for my wallet? Yes. Is it better for me because I'll spend less time in the shop? Yes. Do I really care that the UAW and American automakers are suffering? **** no.
