(Reuters) - A long-term U.S. manufacturing rebound is under way, and it will likely endure because the United States is becoming more competitive with China and other emerging economies. According to a recent report by the Boston Consulting Group titled "Made in America, Again," the cost advantage China has over the United States is shrinking fast. "Within five years, rising Chinese wages, higher U.S. productivity, a weaker dollar, and other factors will virtually close the cost gap between the U.S. and China for many goods consumed in North America," the report said.
