While this doesn't produce necessarily faster people it does block certain genetics in the gene pool from moving forward just because its not institutionary decided doesn't mean its not happening already.

I like that description, it makes a lot of sense but I wouldn't way its more or less virtuous than eugenics. We just love putting ourselves on a pedestal don't we?
