Eugenics is not good idea even on paper, because there is no way future-proof your selective criteria. 100 years ago strong back and dim minds were in demand, now strong minds (and weak backs) are, and in another 100 years entire society might consist of cloned Derids. Even selecting against mental illness is not clearly beneficial, there is research tying a number of mental conditions to over-expression of various g - beneficial genes. (g is general measure of intelligence)

I think it is safe to assume that we want to increase g but alleles that support it have all kinds of nasty side effects. I read papers tying Flynn effect to increase in autism. What if they are correct? Lets say average IQ of American is around 98 and 2% of autism, what if selecting for g increase average IQ to 118 but also increases autism to 20% ? Can our health care system sustain such load?
