Lee Iacocca is talking about the possibility of adding U.S. trade negotiator to his resume. The Chrysler Corp. chairman was in Tokyo Wednesday to announce plans to sell Chryslers in Japan and told the Japanese just how tough a negotiator he would be. "As I have said a hundred times, this market must open up a lot wider to American goods," Iacocca said. "If there were a job that would be of some interest to me and where the world may need a tough-nosed business attitude, it is the trade negotiator. I don't think many countries would like me in that position because I'm an unabashed patriot. I would come home with the bacon for the United States more often than not." Iacocca said he would consider becoming the trade representative "because we have got to right these things, and we have to balance the trade deficit."
