As any real evolutionist or genetic scientist can tell you, it only takes one generation for a new mutation to show up. Encourage that new mutation to survive, reward it economically, and the next generation will have more. Seven or eight generations in, and that mutation may just threaten the rest of the population.
We've got such a mutation today in the United States- the transnational capitalist. A subspecies of homosapiens that is born without conscience or virtue. There is nothing good to say about the transnational capitalist- he'll sell his own relatives for a $.01 increase in share price. He'll let people die rather than see his assets fall in value.
I say it's time to exile these monsters- let some other country deal with them and the carriers that are their totally unproductive family.
