Talking Points

A conversation with Lee Iacocca, chief spokesman and a member of the board of directors of The Online Asset Exchange (onlineassetexchange.com), a service for buyers and sellers of machine tools. Iacocca also is involved with a company that produces electric bicycles. The former president of Ford Motor Co. and of Chrysler Corp. was at WESTEC 2000, where he met with CUTTING TOOL ENGINEERING to discuss manufacturing's role in the economy, his perceptions of the machine tool industry and business-to-business e-commerce.
