El circo (song)
The lyrics describe two brothers, "Carlos" and "Raúl" (in reference to Carlos Salinas de Gortari, president of Mexico from 1988 and 1994, and his brother Raúl Salinas de Gortari), who form a "circus" (a drug cartel) and get rid of the other "circuses" in the country. After the brothers get wealthy, Raúl makes Carlos' money disappear (a reference to the Mexican peso crisis) and their circus ends. Raúl is jailed, while Carlos leaves the country, and the people are finally at peace, unless another circus arrives and the story repeats itself.
Carlos Salinas de Gortari
He negotiated the North American Free Trade Agreement (NAFTA), with the United States and Canada. Critics say that NAFTA has had mixed results for Mexico: while there has been huge increase in commerce and foreign investment, this hasn't been at all the case for employment and salaries. Salinas also renegotiated Mexico's foreign debt.
