"Not even the most exclusive form of segregationism has anything to do with a rejection of free trade and the adoption of protectionism. From the fact that one does not want to associate with or live in the neighborhood of Blacks, Turks, Catholics or Hindus, etc., it does not follow that one does not want to trade with them from a distance. To the contrary, it is precisely the absolute voluntariness of human association and separation—the absence of any form of forced integration—that makes peaceful relationships—free trade—between culturally, racially, ethnically, or religiously distinct people possible."
