Why Trump voters need the immigrants they want to turn away

The irony in President Donald Trump’s hostility to immigration, expressed again in reports of his vulgar comments about Africa and Haiti last week, is that in appealing to the racial and cultural resentments of his political base he is directly threatening their economic interests.

The equation is unmistakable: as America ages, the older and blue-collar whites at the core of Trump’s electoral coalition in 2016 need more working-age immigrants to pay the taxes that fund Social Security and Medicare. CONT.
