I think you are ignoring history. All societies evolve or die and are supplanted by new ones. Don't you suppose Britains were saying the same things about the Angles and the Saxons when they were moving onto the island ?
We tend to get caught up in the idea the way things are now are the way they always will be. That's likely what the Spanish were thinking when they owned Florida, Texas and California.
