At least a dozen years ago, I was reading a sci-fi novel, the name of which escapes me, but there was one line in it that was so profound it literally changed my understanding of human nature.

"You'll never make people stop doing something, until you make them stop wanting to do it."

As long as there is corruption from top to bottom in Mexico, there will be crushing poverty among the people, and millions of those poor will continue to come to the US to try to make a better life for themselves and their families. Only a massive, organized, armed rebellion will ever be able to root out that corruption, and I don't see any chance of the Mexican people having either the will or the ability to ever stage that rebellion, at least in my lifetime. The only hope of a future for Mexico is if their government collapsed entirely, and begged the US to annex them as a territory, but by then we'll most likely be so far in debt to the Chinese that we won't be able to afford to help them in any significant way.
