Former President Donald Trump's promise to carry out "the largest domestic deportation operation in American history" would not only be a moral calamity requiring an enormous expansion of government—it would also be hugely expensive and ruinous to the American economy.
The governmental infrastructure required to arrest, process, and remove 13 million undocumented immigrants would cost nearly $1 trillion over 10 years and would deal a "devastating" hit to economic growth, according to a report published last week by the American Immigration Council (AIC). The think tank estimates that a mass deportation plan would shrink America's gross domestic product by at least 4.2 percent, due to the loss of workers in industries already struggling to find enough labor.
