That's glib.
Mexico has every natural advantage a country could ever want: location, resources, a rich cultural mix, a population with ambition and not adverse to hard work. It's one thing, and one thing alone that prevents Mexico from being successful, and that's corruption. It's corruption on a scale you wouldn't believe unless you've been there; it's corruption that even puts other Latin countries to shame. It's not only government, and the legal system, it's almost every walk of life. Not only will the police will steal the wheels off your car and sell them back to you, but sidewalks crumble, walls flake apart, lumber cracks; you buy a bottle of Asprin at a drug store and you have to check it to see if it's been opened or looted. Everyone cheats everyone down there.
Sounds like you've been there!
