It might surprise some people to learn that there are leftists who are against open borders. Angela Nagle, an Irish academic and writer, is one such person. It's interesting to read her criticisms of globalism, as they reinforce the arguments that we ourselves make.
In 2018 Nagel wrote a piece for American Affairs titled "The Leftist Case Against Open Borders". She observed of the modern left that,
Today’s well-intentioned activists have become the useful idiots of big business. With their adoption of “open borders” advocacy—and a fierce moral absolutism that regards any limit to migration as an unspeakable evil—any criticism of the exploitative system of mass migration is effectively dismissed as blasphemy. Even solidly leftist politicians, like Bernie Sanders in the United States and Jeremy Corbyn in the United Kingdom, are accused of “nativism” by critics if they recognize the legitimacy of borders or migration restriction at any point. This open borders radicalism ultimately benefits the elites within the most powerful countries in the world, further disempowers organized labor, robs the developing world of desperately needed professionals, and turns workers against workers.
She points out that,
Developing countries are struggling to retain their skilled and professional citizens, often trained at great public cost, because the largest and wealthiest economies that dominate the global market have the wealth to snap them up...According to Foreign Policy magazine, “There are more Ethiopian physicians practicing in Chicago today than in all of Ethiopia, a country of 80 million.”
In a piece about her own country, Will Ireland Survive the Woke Wave?, Nagle predicts that Ireland will follow the same path as other Western nations:
As a former colony, historically unsullied by the sins of slavery and imperialism, Ireland’s national identity has been largely free of the culture of pathological self-hatred found across most of the liberal West today...But all of that is about to change.She believes that Ireland is too economically dependent on an international "progressive tech oligarchy" and that,
It will now be a second but no less bitter irony that the native Irish working class will soon find themselves in the same position as the British have — despised as reactionary by our own elites and morally and economically blackmailed into accepting their more enlightened values.
Like all doomed traditions, our banal ethno-nationalism has been passively held by the majority while the intellectual and moral foundations that once justified it have been slowly replaced and degraded while nobody was paying attention. When a full confrontation with the liberal internationalism we invited in during the Celtic Tiger years inevitably happens, those foundations will already be gone and we will no longer be able to explain why having any right to a national culture or national sovereignty is anything other than racist and exclusionary.
