What people forget when they discuss open borders is that the issue is not, first and foremost, about migration. Migration is one of many symptoms. The real issue is the already almost complete porousness of national borders to global capital. The migration flows of cheap, easily exploitable labor exist because they are useful to that capital. Not only because they drive down costs of labor but also because they underscore and reinforce the irrelevance of nations.
Positioning the need for these migration flows as some sort of a humanitarian issue is yet another marketing ploy of “cool capitalism.” Capitalism doesn’t quash dissent. It incorporates dissent into a profit-generating scheme. People feel all rebellious and countercultural when they do the dirty work of capital. It’s very hard to resist the lure of coolness.
