But why in real life your Western world is more like a cancerous tumor, which constantly requires more and more resources and destroys neighboring healthy cells and kills the entire body?
I would argue that this cancer-like spread is inherent in the globalist neoliberalism people like McCain espouse.
When you see everything through an economic lens, seeing individuals as atomized units of fungible labor and countries merely as markets to be exploited, anyone who stands up in favor of the traditional nation-state is a great danger.
Ever notice how neoliberals claim devotion to people in the abstract but always despise those leaders who are most popular with people in the particular (Putin in Russia, Trump in US, LePen in France, Orban in Hungary)?
Globalist neoliberalism really is a cancer.
