The discussion centers on the future of Mexico's government revenue as oil fields deplete over the next decade. Currently, a significant portion of government funding relies on oil, and concerns are raised about the sustainability of this model. The legal framework in Mexico, which states that the government owns all minerals beneath the surface, complicates private exploration and ownership. Additionally, issues like corruption, including skimming of government funds and bribery, exacerbate financial challenges. Despite ongoing geological surveys aimed at exploring untapped resources, there are doubts about the government's stability and ability to adapt to a post-oil economy.
