One of President Lázaro Cárdenas' most impactful policies on Mexico's economy was the nationalization of the oil industry in 1938. This move not only asserted national sovereignty over Natural Resources but also allowed the government to control oil revenues, which significantly boosted public investment in infrastructure and social programs. By prioritizing economic independence and agrarian reform, Cárdenas aimed to improve the livelihoods of the rural population and stimulate industrial growth, laying the foundation for Mexico's development in the following decades.
