A stacker recently reviewed a book by Bryan Caplan supporting open immigration such as illegal or undocumented immigrants from Mexico and Latin America.
He said I find the concept of borders absurd. We asked him why and are waiting for his answer.
Can @south_korea_ln or anyone else explain why borders are absurd and elaborate on their vision of a world with no borders?
South Korea has a border near 38 parallel with North Korea. The Korean War, 1950-53, preserved the sovereignty of South Korea, which is defined by a border.
