The truth is that Ms. Rousseff’s Workers Party has been in power for more than 11 years and has so far failed to establish even a hint of the dreaded dictatorship of the proletariat. On the contrary: The once radical party has come to look increasingly centrist, adopting many of the practices of its neoliberal rivals. It has employed orthodox economic policies in order to maintain market stability; it hasn’t nationalized any assets but rather favored the privatization of ports, highways and airports; and Ms. Rousseff’s new ministers include an ally of agribusiness and nemesis of environmentalists, Katia Abreu, as agriculture minister, and a fiscally conservative banker, Joaquim Levy, as finance minister. This year, the profits of Brazilian private banks increased 26.9 percent. According to the “Top 1,000 World Banks” survey, Brazil is ranked seventh in banking profits.
