Some economists are pushing for "open borders"
What if there was a program that would cost nothing, improve the lives of millions of people from poorer nations, and double world GDP? At least one economist says that increased mobility of people is by far the biggest missed opportunity in development. And an informally aligned group of advocates is doing its best to make the world aware of the "open borders" movement, which suggests that individuals should be able to move between countries at will.
Vipul Naik is the face, or at least the voice, of open borders on the Internet. In March 2012, he launched Open Borders: The Case, a website dedicated to the idea. Naik, a Ph.D. candidate in mathematics at the University of Chicago, is striving for "a world where there is a strong presumption in favor of allowing people to migrate and where this presumption can be overridden or curtailed only under exceptional circumstances."
