"Bullough predicts that the next big thing will be poor countries selling ambassadorships. If you become ambassador to the Court of St James for some tiny island that you've never even visited, you have diplomatic immunity. Or you can offshore your embryo, as some enterprising Chinese officials now do. The husband fertilises the wife's egg, and they implant it in a Japanese woman, who gives birth to their child in Japan. The child has a Japanese passport, a chunk of the family money is transferred to his Japanese account, and now the family has somewhere to flee to, just in case."
