answer:Why would they kill handicapped children at birth, when they have the ability to erase/prevent any sort of birth defect with ease? In any case, you can be guaranteed that such conditions would preclude any sort of deal. You can also be certain that with such a culture, they would not become friends with humanity. They would be seen with disgust and distrust, as well as a threat of such proportions the likes of which is unprecedented in human history, and their technological superiority would only make it worse. And because of the point of not being allowed to own anything, even the ruling political and corporate elite would not agree to this.
