For a government agency that’s pretty much flown under the radar for most of its 80-year history, the Export-Import Bank is getting a lot of attention recently. While its mission is to provide loans, insurance and other types of financial assistance to companies that ship U.S. goods overseas, it’s now at the center of a fight in Congress over the role of government in business. This week on Money Talking, regular contributors Joe Nocera of the New York Times and Rana Foroohar of Time magazine look at why the Export-Import Bank is under such scrutiny and what it means for business in general.
