Insurrance is.
The bad teeth everyone has in the family?
Uninsurable for all your descendants. The mental problems some developed? No coverage of that in life-insurrance - forever for all descendants carrying the genes. More then average aggression as a teenager? Presume your kids on some invisible watchlist.
You are already living in a invisible Gattaca.

Or at least the law as they interpret it. Look at the opioid madness and even with that, I think big pharma was being Lawful Evil. Once the law is determined, I think they follow it. Even though they lobby to change it.
That's one hell of an impressive PR turn around honestly.
Don't get me wrong insurance companies are a problem too, I just can't let pharma off the hook.
