It sounds cruel, but if someone is set on allowing their children to be raised by strangers on the internet and the government, they need to be ready to accept any outcomes that come along with that.
Frankly, (and no, I don't mean this as a flame bait, mods) I see it similar to when alcohol was introduced to the tribes of America, when they were genetically predisposed to both increased intoxication and addiction to alcohol; we introduced smartphones not only to a population that was simply not at all prepared for it psychologically (arguably, genetically too), but it was also introduced largely to the young through the adults, who were even more psychologically vulnerable to every single form of predation and things you would want to protect children from one could imagine.
I know people who suffer from both the effects of smartphones and "social media" (some both, some each) in several ways too broad in scope to detail here now (but it is very bad in many ways), even though the irony in one case in particular that comes to mind, is that it is due to secondary effects from their parents' behaviors, actions, and inactions related to social media and smartphones. To your point, the saddest part is that it is not the "bad parents have natural outcomes..." it is the "children" who are suffering and having to recover from even things like grooming and psychological conditioning, and having to "reparent" themselves following a young life of neglect and what can easily be described as abuse from it.
The challenge presents itself there that barring adults from "social media" and smartphones due to negligence, neglect, and various forms of abuse is a far more tricky issue and topic; especially when a double-digit trillion dollar industry is behind it that makes up what can be argued is the only remaining, functioning industry in America.
I will have to stop here. It has given me an idea for a book. Thank you for spurring that.
Promoting failed parents and children, not in spite of their failures but because of them, is suicidal empathy, a modern mental illness that was never able to fully take root in the past, because the world was always much smaller, divided, and cutthroat.
If given the binary choice between “being an individual” or a “civilization”, I would choose to burn down the civilization in a moment IF it meant the eradication of the individuality of those that I love. I would hope every single person with a heart beating in their chest would feel the exact same way, or else THAT is when a society truly collapses.
To borrow your analogy, the Indians became alcoholics because “they were genetically predisposed to it”? Okay, well why would we want to increase genetic predisposition to alcoholism in the gene pool by denying someone their freedom to drink themselves stupid?
You can argue that it wouldn’t be fair to their children, but those who aren’t drunkards could become wealthy casino owners whose children will prosper more than even you or I, while those whose genes, according to your perspective, apparently don’t allow them to control their own urges will fail, and their lineage will end, along with their hereditary alcoholism.
I see no reason for society to bear any level of responsibility for individuals regardless of context, as society is built by successful individuals , and it is torn apart by failed ones. We must allow the natural outcomes, which is that failed people will fail.
Evolution, if guided by humans, would quickly devolve into chaos, as we can’t accurately select for the correct pressures for success. It simply has to occur. Society is a living organism in the same way.
