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.
History of the Cross Border Xpress
Following Mexico's Debt Crisis and foreign loan renegotiations in the 1980s, in 1989, President Carlos Salinas de Gortari began to implement a massive privatization program to facilitate both the general and regional development of Mexico. Key to that program was the modernization of all transportation networks. Lacking funds and acknowledging the symbiotic relationship between commerce and transportation, "co-investments" were initiated to attract both domestic and foreign capital.
