It is kinda funny that unauthorized migration from Mexico is rooted in the post-revolution land reforms of the1930. Mexican peasants were given land but were poor, so they left to the US in an attempt to finance it.
Eventually this led to labor shortages in Mexico and a booming large scale agribusiness in the US, so the Mexican government began to pressure the US to deport or repatriate Mexicans, leading to the infamous Operation Wetback that many revisionist liberals today point to to validate their claims of eternal White Supremacy.
This irony is somewhat cruel and persists today. The Mexican government actively welcomes Mexicans to return while American businesses secretly love the practice.
