Summary: We need four bales of cotton to make the Planet Money t-shirt. On today's Planet Money, we go shopping in Texas and Brazil -- and find a long-running trade war. We meet a Brazilian who took on the world's largest superpower, a Texas cotton farmer who's tired of hearing the Brazilians complain, and a guy named Renato -- a.k.a. Retaliation Master. Music: Johnny Cash's "Cotton Fields"
