PResident Donald Trump To promise to revitalize American manufacturing. Its radical prices are intended to bring up businesses to reshape their operations, transforming America into industrial superpowers. Mr. Trump’s message is attractive because he draws from nostalgia for an era when blue -collar could win middle class wages that get up on a mounting chain. In 1950, almost one in three American workers was employed in manufacturing, against one in 12 today. But the president’s efforts to restore America to its former industrial glory represent a fight against the powerful long -term economic forces.
