The 56-year-old conservative businessman Mauricio Macri has become Argentina’s President for the next four years. After taking the oath of office in Congress, he received the presidential sash in the Pink House in a festive atmosphere without the presence of outgoing President Cristina Fernandez. After the party is over he will have to deal with problems such as a spiraling and out-of-control surge in prices and the effects of the devaluation he has announced, which will undoubtedly erode the buying power of millions of working class families.
