Well, to start off, no disrespect, but dont know what you are talking about. That "garbage Jeep line" as you called it, is the bread & butter and is providing the bulk of Chryler's unit sales, and its actually a very nice and popular line.
Back to the issue of building Jeeps for China. I am not going to go back and find the video ad to rewatch it,but unless it specifically says "EVERY JEEP THEY SELL IN THE WORLD WILL BE MADE IN CHINA", then it at least partially true. Once again, Chinese love Jeeps...yada yada yada,so we COULD,theoretically, EXPORT THEM TO CHINA. That would mean, BUILD THEM HERE,and hire more employees, then SHIP THEM TO CHINA. Instead, their plan is to build a plant in China and hire Chinese to build them. That DOES IN FACT COST AMERICAN JOBS,spin it anyway you like.
Now, I suspect,and am no expert in this area, but I believe that they want to build them there and sell them there because it would be cheaper than exporting them to China do to export tariffs placed on us by the other countries
