Brazil's President Rousseff attends a meeting of the Brazilian Forum on Climate Change in Brasilia

As the World Cup kicks off in Sao Paolo this week, the home team is the runaway favorite, with a 45 percent chance of winning the tournament, according to Nate Silver on FiveThirtyEight and 48.5 percent probability according to the statistical boffins at Goldman Sachs. But apart from the bookmakers — who stand to lose a fortune if Brazil wins, since they are offering odds of around 3 to 1, instead of the 1 to 1 suggested by Silver’s and Goldman’s calculations — another, more surprising, group is secretly rooting against the favorite: Brazil’s own financial and business community, along with much of the country’s middle class.
