Trisomy 21 (Downs) is more controversial, but the screening are decreasing numbers, even if many people disagree with this screening. The main issue is the level of severity varies greatly, many DS folk are able to live happy an fulfilling lives.
I think this is what makes so many AS people shy away from eugenics, autism is also a spectrum and stories of uncontrollably violent teenage autistics who have 12 hour long meltdowns and destroy the house and stories of autistic savants/geniuses like Tesla and Warren Buffett seem to cancel each other out. If you say, well where would we be without Tesla, some of these warrior mothers pull up blog after blog on their computers of women who have been mentally destroyed by very violent autistic boys. If the mothers say, wouldn't life be better without violent, destructive auties, we start babbling about Tesla.
That said, I have seen case after case of behavioral patterns in certain families repeating themselves from generation to generation. This is especially notable in cases of teenage parenthood, some families seem to be locked into a pattern of having babies as teens. At the other end, you have families like the Rockefellers and Rothschilds who have held onto their wealth and increased it down the generations, while most "average" people who manage to acquire wealth via successful businesses have the wealth disappear after a generation or two.
