I always saw England as Greece, the bearer of culture to the world, and America as the Roman Empire, powerful with serious internal weaknesses. The Roman Empire did collapse while Greece, like modern England, slowly faded away...
Of course, there is a Darwinian argument that could be made here. If Hispanics are more numerous and the whites are generally only interested in luxuries and not producing offspring don't the Hispanics "deserve" the Southwest? Philosophical question of course...
The thing to keep in mind, which folks don't seem to realize (yet), is that this type of border immigration situation really picks up speed exponentially. It will suddenly seem to grow by leaps and bounds, and before you can say "Roberto es me Tio", you are living in Amexica, with "Spanish Only" laws, etc.
We are in the beginning stages of that "takeoff phase", and "we ain't seen nothin yet."

Very good question. It is a fact that groups of peoples have been migrating hither and yon all over the world since the beginning of time. Heck, there is strong evidence that there were other folks in the western hemisphere before the Indians migrated here from Asia. But, it is also true that strong cultures live on to influence future generations even if it is defeated militarily and politically by a lesser culture at a given time. Example: Roman and Greek culture have a far more profound influence on political and cultural life of Europe and America than that of the Angles, Saxons, Visigoths, Ostrogoths, and other Germanic barberian tribes, even though they overthrew the Roman Empire for all practical purposes. My obsession these days is not to let my culture, which I think is superior, be overthrown by that of a bunch of barberians like the Romans were. Fact is what lead to their downfall was letting the Visigoths settle within the boundries of the empire and govern themselves when they needed refuge from Attila the Hun. Sound familiar???? We have here past history to take heed from. If we don't do it, then maybe we do deserve to be wiped out.
