It’s not Paris or Tokyo, Beijing or New York. Nor is it São Paulo or Rio de Janeiro. Enthusiastic residents of Porto Alegre, Brazil will tell you that their modest city of 1.5 million people in the country’s deep South is “the last bastion of socialism and rock ‘n’ roll.” Indeed, stalls covered with black Iron Maiden t-shirts stand in the public markets, and the municipality long served as a stronghold of the Partido dos Trabalhadores (PT), the Brazilian Workers Party. But today Porto Alegre is best known around the globe, especially among those inclined to hold a critical opinion of capitalism, corporate power, and U.S. military aggression, as the original home of the World Social Forum.
