Throughout his campaign, Donald Trump promised to revolutionize trade policy for the benefit of American workers and industry. He should begin by stopping the Export-Import Bank from purveying corporate welfare.

Ex-Im is a federal agency established to help American exporters by providing taxpayer-backed financing to governments and businesses in developing foreign markets without access to the necessary means to buy American products. In its youth, Ex-Im did just that and bolstered exports in the interwar period to Cuba, Haiti and Burma. Over the last 50 years, though, it has ventured far from its original purpose and has become a vehicle for ruinous market distortion.
