A supporter of NAFTA, Bartley is said to have observed to a former colleague, Peter Brimelow, "I think the nation-state is finished." Alongside his support for the free flow of goods, Bartley supported the free flow of labour across borders. He controversially wrote in favor of open borders and high rates of immigration to the United States. After then Mexican President, Vicente Fox, declared in a speech in 2001 that "NAFTA should evolve into something like the European Union, with open borders for not only goods and investment but also people", Bartley wrote in support of having open borders between Mexico and the United States.[7] Indeed, in that July 2, 2001 Wall Street Journal editorial, Bartley reminded readers that "during the immigration debate of 1984 we suggested an ultimate goal to guide passing policies--a constitutional amendment: 'There shall be open borders.'"[8]
