Evolution question

Idealistically, a world free of congenital diseases would be a miraculous one, but the means needed to create such a world are far too severe to partake in. First, people have to decide what congenital diseases the world will be better without, and then comes the question of who is allowed or not allowed to reproduce. And does anyone have the right to restrict the ability of someone else’s reproductive success? In the past, the United States was home to a world of eugenics. According to the nature.com article on Eugenics, the American movement took place in the early 1900’s. In theory, the idea of selecting more desirable traits to rid of certain diseases sounds like a relatively good idea, until you take into consideration the means at which this would be accomplished. The eugenics movement involved many cases of involuntary sterilization and institutionalization. During this movement, we lacked the vast knowledge of genetics and genomes, so they believed certain qualities such as alcoholism, “criminality”, “feeblemindedness”, and epilepsy were traits that possessed a great genetic basis, which is not wholly the case. Also, if these were the traits thought to be undesired, which there are likely many good reasons one might not want to possess them, one can only imagine what type of traits might be considered undesirable now.
