If Vicente and other Mexican leaders had done a good job, their citizens wouldn’t be trying to leave that hellhole.
What is the problem with Mexico? Are their people too stupid to run a successful economy? Do they not have resources? I believe their problem is racism. The Mexican leaders of European ancestry want all the indigenous people to leave. They have treated them very poorly. They don’t educate or do anything to help them. They encourage them to leave so they can have their European dominance.
Racism, caste system. The elite in Mexico will do without infrastructure, services, etc. in order to keep the poor from having a real job in order to move up.
There is no real middle class in Mexico- rich and poor. As you say they push their poor on us.
The only way to advance in society in Mexico is through crime, that is why cartels are so powerful. You can’t even marry your way up in Mexico, if a poor person marries a rich person the rich person is disinherited by their family.
