I strongly disagree with many of the claims being made on here.
IMO...
It doesn't have anything to do with God, whichever flavor you prefer.
It doesn't have to do with 2 parent households, shitty parents exist they always have, and they exist on this forum, and they likely don't realize they're shitty parents, and there's nothing you're going to do about it.
It doesn't have anything to do with soccer, or movies, or video games, teachers or babysitters.
It doesn't have anything to do with your definition of morality, religion, or preferred version of history.
The best arguments are that we don't actually have a problem, "we" are simply fabricating one to fill some psychological void. A 1:10,000,000 event is not a real problem it's a black swan event. It's an unfortunate occurrence, often times tragic, and even if we analyze each one and determine that each one would have been preventable if..." ". They're not actually preventable because you don't prevent 1:10,000,000 events. Throw in that our current technology has allowed more free time and more ability to see terrible things that happen (while completely ignoring the 9,999,999 other events) and you've got a recipe for unnecessary social unrest.
If someone where to try and convince me that "something" was actually happening I'd lean towards it being way simpler and less definable. I think one might argue that we're simply seeing natural selection at work. Nature has all kinds of self-correcting mechanisms that we don't understand, and they don't all have to be physical attributes. We should expect to see more things that kill lots of us (disease, war, behavior, etc). Humans cannot like forever, cannot grow forever, and our species appears to prefer to burn the candle at both ends. We've massively constructed lives and societies that simply aren't resource sustainable. We've boomed, and now-maybe, we'll bust.
