President Trump's immigration crackdown has not expanded job opportunities for American workers, a new study found — in fact, it's associated with an employment drain for some U.S.-born men.

The research, published in the National Bureau of Economic Research, found that ICE activity led to a "negative and significant impact" on employment of U.S.-born working men with at most a high-school education. Sectors like construction were especially affected, according to the working paper.

Authors Chloe East and Elizabeth Cox analyzed the national labor market effects of the Trump 2.0 ICE blitz. Their results showed no evidence that employers raised wages to attract U.S.-born workers; instead, overall demand decreased.

The narrative that undocumented immigrants take Americans' jobs has long fueled the administration's enforcement push. This study suggests the opposite: mass deportations may actually harm the very workers they aim to protect.

Caveat: The paper is a working paper and has not yet been peer-reviewed. Other factors outside of ICE enforcement could also influence these employment trends.
