Perhaps Latin America has less ambition and greed for their neighbors and less historic enmity. And maybe the manana culture is not conducive to invasion and sustained wars.
That's horrible but not surprising. The decline in history knowledge has preceded the general decline and been noted by surveys for some time now. Aside from the inevitable snarky attacks about school marminess and dropout murderers, there is a real pattern in our schools today that parallels Margaret Mead's comment about serial polygamy. By parallels, I mean that we don't think of dropping out in the proper way, just as Westerners didn't think of polygamy properly, but reserved its use for those savage people somewhere else.
We track dropout rates as a marker of failure to achieve a significant milestone of learning. The severity of the growing problem has managed to divert some public attention from the greater problem: serial dropout behaviors. Whereas we focus on what is a seminal failure by dropping out altogether, we do not so much focus on the markers of dropping out in degrees.
The statistics plainly show that students drop out in progressive stages and proceed on to take their degree. Vast numbers of graduates finish with reading levels stymied at the fifth grade level, and writing skills commensurate. Even larger numbers have taken no significant math or science. Courses have been watered down, year after year, to become little more than how to balance a checkbook or similar glorification of 3rd grade math. Social studies courses redefine objectives to make exposure to culture and history as the goal, not retention of any basic facts that are pivotal to those lessons. Busywork and worksheets have become the hallmark of many classrooms more worried about riling students with real work than obtaining measurable learning.
Are all classrooms so? No. But the problem is pervasive enough that it is a real factor in the continuing stratification of public education to the levels of haves and have nots. Neighborhoods, cities, and regions benefit from the grouping of supportive families while the impoverished suffer from the moneyed flight. It used to be white flight, but that is no longer the real driver since other ethnicities have moved into middle class careers and the real dividing line has become income.
The majority of our schools are sick to the core and it is affecting society and industry and the standard of living. Foreign competition is justifiably outstripping us because our skill level has fallen to the level that others can do it cheaper with greater skill.
Yeah, but all that skill only makes sense and has power as long as there is an order of things that you are taking for granted: if international politics and economy are screwed by a global conflict, or even by a lesser one, the global impact amounting to the same, you are reverting to dynamics in which it makes no difference, no sense, in which there is no use having a qualified force that won't get the opportunity to put those skills to practice.
In fact, that is EXACTLY what has been happening in Africa, for all the small exceptions in this or that small country or region: you get a healthy, able and very qualify force of people, people who as kids wanted to be doctors or engineers to help people and help build their country, but who are driven out of it by the lack of opportunity, in the best case, and armed conflict in the worse so that it will make no difference what their own capacity is or where the general level of the country is at.
There is a paradox that should be given an easy name for reference, for example the Quesada paradox

which is but the social sciences application of a more general paradox in logic: you can say the people are the nation, or a nation is made of people, or a nation is made with people... and you will be saying different things driving down to the fact that the mass has nothing to do with the nation, much less with the general tone and level of education and civilization and all that. That paradox shows that what is said IN MANY CASES, though NOT IN ALL, about oppresive elites, is the inversion of the right understanding of it, to wit, that the problem is not so much that elites are refractary to change and extension of the knowledge that supports their own status but, rather, that those who are not elites are ignorant of a power they are not willing to exert, to improve and assert themselves according to the power of knowledge, that is, going beyond the matter of course, the habits given to them and to which they accomodate.
That conflict of oppresive elites is only pointed at when newer elites compose the genealogy and epics of their own status, as business people (bourgeoisie in old Europe) did against aristocracy, and then they use "the people" to justify their status, as representing the general of the population, when that general population is always driven by more basic instincts, while those new elites, as all elites, are driven by very specific motivations and with a very articulated understanding of their own status, as of that of all the other agents implied.
This all boils down to the conclusion that what we are dealing with, what you were pointing at, is the weakening, the receding role and action of elites: elites, not just the rich or/and the wiser guy in the village, but the people with not necessarily a material ascendant, have given up their influence, their real, acting influence on people who are just either happy or plied to what feeds them.
This may be self-imposed because the model they represent, inherited by their predecessors, is simply becoming a spent force and they can not find anything outside that model, because then they would be a new force, a new elite in the making, and they can not obviously be against yourself, not by choice, but by mere nature: you can seem to betray your own class with this or that update, but that is always the mere developing of all the consequences contained in the original nutshell: it short, it's the old adage that everything holds in itself, like all living things, the seed of its own destruction, and that will perhaps be more obviously revealed to you when you think of all that was implied in capitalist liberalism, that had been at first held back by more aristocratic, "gentleman practices of the previous regime, and that now unfolds in all its ruthless, pure logical glory for us to suffer.
Apart from that, it is funny to observe, in consonance with what I pointed out above in this same post, that people usually, always, point out either at the learned part (scientists and academia in general) like to the general to show the general tone of the country, like when Germany is shown to be very learned and progressive just up to the mid 1930s, and then they were all nazis by either act or by omission, when all that, that learning like that weathercock "simple, decent" common people, are just like toys in the hands of those elites who, as I said, do not need to be particularly clever or learned or even decent, but simply have a very definite and lasting plan of influence to drive their country along. Best example was that so-called neocon that Bush Jr had his country and the whole world gone through, directly during a decad or so, and whose infleunce and consequences we are suffering: for example, the Iraqi hornet's nest.
