Actually, the Numbers Show That We Need More Immigration, Not Less

“Unless American birthrates pick up suddenly and expand the work force — an unrealistic assumption given that the country just set a record for low fertility — or the productivity of its dwindling work force quickly doubled, only slightly less unrealistic, says Mr. Goldstone, the United States will be staring at real G.D.P. growth of less than 1.6 percent per year in less than a decade, all else remaining equal. America should be admitting a million more immigrants per year — more than double the current number from now until 2050. This still won’t add up to mass immigration because it would put America’s foreign-born population that year at around 26 percent, less than Australia’s is today.”
