Since the 1940s, Mexico began a complex path to overcome the material and managerial problems left after the Mexican Revolution and the expropriation of the late 1930s, with a state apparatus in formation, scarce technical personnel, and high illiteracy of its labor force. For this, the path taken by the Mexican government was to resort to the resources, models, and advice of the United States at a time when it was rising as a global economic, industrial, and military power. The opportunity arose during World War II when, in 1941, Mexico received U.S. advice to improve its transportation capabilities and join the war effort, opening assistance for future and diverse projects that the federal apparatus managed through decentralized agencies. This chapter presents an overview of some public industrial and infrastructural projects that resorted from technical assistance of U.S. forms of consumption between 1940 and 1970 to create a new “national” materiality and spatiality. We consider for the analysis the public project as a valid scale to understand the vectorial character, although negotiated, of the relationship between Mexico and the United States in the framework of the Cold War, which was not opposed to the strong local economic nationalism promoted by the Mexican political regime that, in the long run, benefited materially and politically from that relationship.
