Imagine a world with literally no borders. It’s a world where the economy is a lot stronger.
Forget, for a moment, about Donald Trump and his calls for a Mexico border wall and a ban on Muslims coming to this country. Imagine, instead, the opposite: We welcome any and all immigrants who want to come here, with no restrictions on visas and passports. Imagine, too, that all other nations do the same, that everyone can move wherever they like. There are no borders. Anyone can move, live, and work wherever they want.
