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.
Economic history of Mexico
Under President Carlos Salinas de Gortari Mexico campaigned to join the North American Free Trade Agreement with the expanded treaty going into effect in Mexico, the U.S., and Canada on January 1, 1994. Mexico implemented neoliberal economic policies and changed significant articles of the Mexican Constitution of 1917 to ensure private property rights against future nationalization. In the twenty-first century, Mexico has strengthened its trade ties with China, but Chinese investment projects in Mexico have hit roadblocks in 2014–15. Mexico's continued dependence on oil revenues has had a deleterious impact when oil prices drop, as is happening 2014–15.
