A couple things come to mind about this:
1. Mexico should be rich. They sit on massive gold, silver, and oil reserves (along with other commodities), have pristine beaches, massive commercial/recreational fishing possibilities, and wonderful potential range and agricultural land. They also have great tourist potential for the same reasons and because of spectacular historical locations. Why are they not rich? Well, because their culture is corrupt and pathetic. Ergo, said culture is nothing to celebrate.
2. The Spanish have no greater claim to the lands of the USA than the anglo-americans. Sure, they had some scattered settlements in the West a little earlier than the anglos — a nothing in time in the scale of history. More over, they lost the lands fair and square, were paid for them, and had failed to develop the lands in any meaningful way. Indeed, Texas became Texas almost by default simply by anglos moving in to the vaccuum.
3. The Indians of Mexico have no claim, at all, to the lands of the USA. They were a more-or-less settled farming people just exactly where they are now.
So, is Absolut going to use the same gimmick in Germany, using a 1943 map of the Reich?
The Russian River in Sonoma County California was named for the....Russian settlers! They had a fort there (can still go visit). It failed.
At least the Russians have the self-esteem not to continue whining about losing California and Alaska.
I think you’ve nailed the Mexican failure to develop their resources because of their culture.
In an Absolut World ESPANA would still own that land.
