Trump wants to stop the flow of illegal immigration, but his chaotic and impetuous response won’t fix the problem and will cause new ones. Trade in goods and services totaling $1.7 billion flows through the border every day. As America’s third-largest trading partner, Mexico is partly responsible for vehicles Americans drive, clothes we wear, electronics we use and food we eat. Our companies depend on Mexico for parts and goods they need, and our farmers supply Mexico with corn, soybeans and more. The last time the border was partially closed, after the 9/11 attacks, backlogs and economic losses were significant. If the border were shut now, there’d be a sudden interruption in the U.S. supply of auto parts, which could halt production within a week. Trade in apparel and electronics would take enormous hits. Forty-four percent of our fruits and vegetables — including avocadoes — come from Mexico. If the border closes, expect prices on produce to rise. Beyond that, 5 million Americans have jobs connected to commerce at and travel through the U.S.-Mexico border. Everyone from truck drivers to port personnel to local small-business owners would feel the pain. And there would be ripples through other industries and the stock market. Little would remain untouched. These are key issues for Trump, who highlights U.S. economic gains every chance he gets, and who counts farmers and manufacturing workers as key supporters. Even if Trump tries to implement a full or partial border closure, logistical complications and legal challenges could make it difficult. And since there’s no way to close the entire border, it’s probable that illegal immigration would continue even if ports of entry are shut. The spike in the number of migrant families crossing the border is an overwhelming humanitarian problem that requires comprehensive solutions. This isn’t one of them. Trump has said he is “not playing games” about shutting the border. If he follows through, the country stands to lose.
