In a provocative new book, Jason Riley makes the case for welcoming more legal immigrants to the United States. Drawing on history, scholarly studies and first‐​hand reporting, Riley argues that today’s newcomers are fueling America’s prosperity and dynamism. He challenges the prevailing views on talk radio and cable TV that immigrants are overpopulating the country, stealing jobs, depressing wages, bankrupting social services, filling prisons, resisting assimilation and promoting big government. Comments will be provided by one of the nation’s leading political analysts.
