The Mexican Aristocracy should be stepped on.
Mexico really needs to reform its asinine "nationalistic" corporatavist laws that would make Mussolini proud. Having a close economic relationship with the largest economy in the world means nothing if it is difficult to own property or enterprises outright and the laws encourage "locally owned" monopolies in the guise of "protecting the people."
Were it not for being next to the US, Mexico would be Bolivia (which also has oil, but is a real basketcase), though not quite Haiti.
