Much obeisance is paid to the need for "multiculturalism" in the school curriculum. How else, ask earnest disciples, can educators promote a sense of empowerment and worth in all Americans? How else can they truly engage the many communities they serve? How else can they run schools that are strong and accountable community institutions?
All that is true enough. But this comprehension and valuing will not change the fact that groups, be they clans, tribes or nations, compete for limited resources. And to the extent that these resources are limited, they do so at one another's expense. For instance, geographic territory is limited; and the demand for it exceeds the supply. It's a zero sum game. Consider the nearly three quarters of a century struggle between Israeli Jews and Palestinian Arabs over land. Think the Palestinians are going multicultural and recognize Jewish holidays anytime soon? Or how about Russia's invasion of Ukraine? Far from honoring Ukraine's culture, Putin alleges it doesn't even exist. Are the Ukrainians going to go for that kind of multiculturalism?
This competition for limited resources is one thing that strictly defines multiculturalism's limits. Why? Because it is difficult to even tolerate, much less honor, another group when that group's gain has been your group's loss. Competition for resources, be they jobs, desirable territory, natural resources, and so forth, has existed for all of recorded history. And, be assured, that this competition will continue, "... for as long as grass should grow and water flow."
Now, in polyglot nations like the U. S., Canada or Australia, token recognition of the other guy's culture is de rigueur. For example, despite the vitriolic distrust and outright rejection that greeted Irish immigrants when they first arrived in the U. S., lots and lots of folks now wear green on St. Patrick's Day, perhaps eat a couple of those horrid confections, Irish Potatoes, or watch the parade. But that's only because the Irish have been so absorbed and intermarried that their presence is no longer the threat it once was seen to be. They now are a part of us. And social science reveals that it is expressions of difference that result in negative appraisals.
Here is another strict limit on multiculturalism. Often one culture's values are diametrically opposed to those of another. Thus, they are utterly incompatible. And that leads us to the biggest problem of them all. The very tolerance required for a group to be multicultural is not only absent, but utterly rejected in many other cultures. Consider Saudi Arabia, for instance. They are so sure they are right about all sorts of things, religion for example, that they make no accommodations for difference whatsoever. Yet this fundamental incompatibility of multicultural tolerance for an intolerant culture is seldom, if ever, recognized by right thinking multicultural advocates.
Sure, if another group's culture has been thoroughly adulterated by elements of the polyglot host culture, modest tolerance toward that other group's culture is likely. But even a long-resident group will still catch a world of crap if they remain sufficiently different. For instance, recent unprovoked assaults on Asian appearing citizens demonstrate that these Americans are sometimes punched in the face, beaten up, sometimes even killed, just for looking different. And if a group who wants to enter is really different, say, Middle Eastern Muslims, one quickly sees how minimally "multi-cultural" the rest of us are prepared to be. Remember Trump's attempted muslim ban? What kind of multiculturalism did that amount to? Then there is his border wall welcoming "the tired, the poor, the huddled masses yearning to be free."
Can one group's culture be enriched by welcoming another group and adopting, or at least respecting, aspects of their culture? Sure, it happens all the time. Nevertheless, due to the dynamics just described, this adoption will often be limited to the dominant group gingerly granting mere token recognition. For instance, deciding that their vittles are tasty.
So, to be realistic, advocates of multiculturalism, in education or out, must limit their ambitions and recognize the limitations. Too frequently that's not happening because of virtue signaling and imbalanced zealotry. Yet this is far too important an issue to address so thoughtlessly. The very growth, enrichment, coherence and stability of our society are at stake.
