Unfortunately, it would not be possible for the parents to obtain the informed consent of the child before undertaking the experiment. Nobody yet knows whether superior genes exist or how they might be identified. But the progress of knowledge of human genetics is rapid, and the technology of reprogenetics will not be far behind.Silver believes that, as far into the future as he can see, the technology of reprogenetics will be expensive. He sees a possible long-range consequence of reprogenetics to be the splitting of humanity into two species, which he calls GenRich and Naturals. GenRich are people who can afford to give their children genetic enrichment. Naturals are those who are left behind. After a few centuries, the division between rich and poor might become hereditary, and the two classes might cease to interbreed. All economic and political power would belong to the GenRich. Naturals could not compete in the market for influential jobs and would have to be content with the station in life to which their genes have called them. Human society would once again be divided into master and slaves. Silver warns us that this nightmare could become reality, if a free market in reprogenetic technology were carried to its logical conclusion. I am imagining a different view of the future. I consider it unlikely that reprogenetic technology will remain permanently expensive. Most of our socially important technologies, such as telephones, automobiles, television, and computers, began as expensive toys for the rich and afterwards became cheap enough for ordinary people to afford. It usually takes about fifty years for a new technology to become generally affordable. Television took less than fifty years; computers may take a little longer. I do not see any reason why reprogenetics should depart from this pattern. At first, reprogenetics will be expensive for the same reasons that in vitro fertilization is expensive today. It is done by specialist medical doctors and highly trained technicians, it requires long hours of their personal attentions, and demand for the services exceeds the supply. After fifty years the situation is likely to be different. Procedures will become standardized and largely automated. Rich patients will still pay more for personal attention and privacy, but clinics for poor patients will provide standard treatments at reasonable prices. It is possible that clinics will supply take-home do-it-yourself kits for parents who are willing to learn the necessary skills. Having reprogenetic babies at home might become a popular hobby, like desktop publishing today.Silver expects that an effectively free market in reprogenetic technology will exist, at least in the United States, and that efforts to prohibit or restrict its use by parents will not be successful. He expects the technology to remain in private hands. American traditions encourage the replacement of public services by private institutions. In the United States, private universities have more prestige and more resources than public universities, and the idea of a national health service is strongly resisted. But in many other countries, higher education and health services are provided by the state, and traditions favor the maintenance of high-quality public services.When reprogenetic technology becomes available, it is likely that many countries will decide to make it available to citizens as a public service. Where it exists as a public service, it may also be available in a deluxe private version to the rich, but the private suppliers will not enjoy a monopoly, and the rich patients will not have it all to themselves. In countries where everyone is legally entitled to reprogenetic technology, a division of society into GenRich and Naturals is unlikely. Even in the United States, if the beginnings of such a division become clearly visible, public outrage could put an end to it, just as public outrage put an end to slavery. In the 18th and 19th centuries, slavery was defended by believers in the free market. Abolitionists decided that the free market should not extend to human bodies, and their view prevailed. I hope and believe that our descendents will decide, in the fullness of time, that the free market should not extend to human genes.
