Eugenics/Designer-babies... is the concept really that bad?

[Astonished]

Exercise a little critical thinking. If people aren't getting sick, they're not dying, living longer, consuming more resources, and generally more likely to do lots and lots of fucking. Overpopulation would become the one 'disease' that can't be overcome. Building in a safety net against that would be the only logical thing to do rather than asking people to use their own discretion in birth control and contraception. If all the important shit is done in a lab anyway, fertility doesn't seem to need to happen anywhere else. Besides which, as I mentioned earlier, parents can be screened and evaluated for fitness in child-rearing so that unfit and abusive parents or those in an unstable and financially rocky situation don't end up with kids they can't properly care for. There's literally no downside to this.

Where on earth did you get the idea that health and economic prosperity correlates with having too many children?

People simply aren't capable of being responsible for their reproduction. I suppose you could program into them a decreased sex drive or amp up intelligence to the point where they'd be too far above that to be careless about birth control but one would think a simpler means would be turning their fertility switches to 'off' for the majority of the time until they decide they want kids and could prove to the current scientific experts that they're qualified. No 'accidents', relatively few unwanted children or orphans, much greater opportunity for successful adoptions, I mean, I really can't see a negative here. What's so bad about regulating population growth in a way that's already being used to enhance the species' genetics in the first place, if it makes people's choices about it (not needing protection or worrying about getting knocked up or spreading STDs) a non-issue?
