With the Trump administration imposing tariffs on steel and aluminum globally, positive impact has been clearly felt on the U.S. steel industry. Anbound researchers observed that the U.S. steel companies committed to heavy-industry bases have invested in full production. The scenes of smoke billows from steel plants remind one like China of the past. The recovery of the steel industry will directly generate benefits for 10,000 to 20,000 America's manufacturing households. Meanwhile, the current U.S. economic structure is dominated by service industries. The U.S. steel industry as a symbol of traditional manufacturing may enjoy a short-term boom, but depart from its economic structure. Whether or not its steel industry will keep booming, it is questionable.
