Summary:
Rise of Internet -> 4chan
Funded abortions -> careless youth (sexually) and possible "behind the scenes" genocide (One said "out there" theory. Slow process, but keep the numbers in check until a "big reveal".)
Social Virtualization (certain ero games and such) -> lower social interactivity / greater dangers to society (I know, but it's among the listed possibilities)
Better healthcare -> more youthful (as well as young-minded adults) recklessness
Automation -> quality control (to better the income of the producer at the expense of the consumer)
The list goes on. It's simple, think up any kind of advancement, and think of the social consequences in which morals are involved. Take it to the most extreme; and now you have a bad-case scenario. If you can top that off, then it's a worst-case scenario.
your list -> full of crap.
Internet is used for more good, and well, anything, than harm.
Teens have, and will, always be careless. Trust me when i say that teens don't think "oh no, i couldn't get a free abortion", nor would think "oh yay i can get a free abortion". it is the last thing on their minds.
Society doesn't seem to be becoming less interactive. 20 years ago the nerdy guy sat in the library and read books. now he can go online and talk with people who interest him etc. And despite the whole fear of it somehow impacting people, i have seen 0 evidence that it is effecting any disprortinate number of people who i've been growing up with/around.
Young people have always been reckless to. We have free healthcare here, yet i don't see people always going around doing stupid shit to the level of, say, jackass. Maybe, just maybe, its your culture that causes that kind of thing to happen.
Perhaps automation might not make every single thing as good as a human could make it with their hands. but that's assuming that the particular human your hiring actually gives a crap, or isn't having a bad day, or has some kind of sickness etc. Machines might not make stuff as good, but it is good enough. Eg, having a pot made accurate down to the mm isn't really going to kill you either way.
I think your just being a little cynical here (and that's coming from me, a cynic)...
