Manifest Destiny

Up until and during the time of Manifest Destiny nearly all of the world, and indeed Mexico, had been impoverished and despotic. Had there not been America inventing electricity, fomenting industry, and developing the idea of democracy, Mexico would undoubtedly still be medieval. And, had Mexico controlled and populated Texas and the Southwest of America, there is absolutely no reason to believe that these areas would be different than the rest of Mexico. In other words, the spread of Anglo American culture from sea to shining sea did enlarge the area of the world that was wealthy, democratic, rights recognizing, religiously free, and with free speech.
