Bingo. When I’ve had discussions (i.e., arguments) with Mexicans about the U.S. stealing the Southwest from Mexico as a result of the Mexican American War, etc. and their desire to return it back to Mexico, I often state that they would have to reimburse the US for all the improvements done for the past 150 years, etc. Of course they get furious. Then I mention that if returning it to Mexico is such a good idea, why did 20% of Mexico’s population come here illegally looking for jobs, benefits, criminal enterprises, etc. Silence. Then I ask if returning it to Mexico is such a good idea, then you’ll see what was once a greatly improved, highly productive area of the U.S. turn into a complete mess as is Mexico. Silence. Last but not least, if we give it back, a wall 20 feet high will need to be built with full security along the entire length of the border since it too will fail, as has the rest of Mexico’s economy, and well, I don’t think we need anymore invaders with ridiculous demands for the balance of the U.S. Silence, indeed.
Remind them if they want to surrender their property rights as land owners given them by the US, and return to the Spanish Land Grants only provided by the King, which can be removed by the King at any time.
Don’t forget to mention that the Mexicans should give their country back to Spain, so that they can give it back to the Aztecs, so they can give it back to the Mayans, Olmecs and Toltecs, who can give it back to....
They act the same in places like New York, never part of a Spanish colony.
