no that's part of natural selection. it's our biology telling us what we want. eugenics is systemic planned pairing and breeding. it's also had the ideas that a person's quality is defined at birth baked into it from the start. it's based on the concept of a person's worth being defined by the circumstances of their birth and not by their efforts in life.
also, actual science tells us that the best thing to "breed for",if that's the way you want to look at life, is genetic diversity. the healthiest stock has the most diverse gene pool. something every eugenicist also somehow manages to ignore that and deny that if improving or genetics is our goal we should be trying to all become a neutral brown and choose people the most different from us genetically.
cause that's the thing about dog breeds. we can engineer the perfect biological hunting machine... that dies by age 11 at the latest. because breeding for a trait never creates healthy offspring. which makes sense, we weren't breeding for health. the natural desire of most parents is a healthy child. it's what nature optimized for. when we start looking for other traits we tend to fuck it up.
