An article by Washington Post columnist George Will spurred Adaptive Complexity's Michael White to wonder why US immigration policy works against retaining PhD scientists. Instead of making it easy to hire educated immigrants, the US ships them off to places like Canada and Europe, where immigration law is less stringent. White agrees with George Wills, whose idea is simple. "U.S. policy should be: A nation cannot have too many such people, so send us your PhDs yearning to be free," says Will.
