“I regard open borders as the moral imperative of our time. [M]odern immigration laws may be ever so slightly more malleable than the colour line, but it remains that the typical citizen of a developing country has a near-zero chance of ever living and working in a country where they can realise their full potential. The economic implications alone are staggering: immigration policies consign millions to lives of poverty based on nothing more than an accident of birth.

There is no moral justification for what we do today. We purport that all human beings are created equal, and yet we arbitrarily agree that some human beings have more of a right to work and live in certain places than others. [T]he case against immigration restrictions is simply an extension of the case against slavery and the case against racial segregation.”

— John Lee, “The arc of the moral universe is long, but it bends toward justice.” (Open Borders: The Case, October 11, 2012)
