How would the parents know? They're just kids that happen to have been alive long enough to gain some stupid legal rights and to have some sex and get pregnant. I've personally (anecdotally) observed that it's the person and their mindset, not age, that determines how well they understand the world around them and the consequences of their own actions. I know adults who are far more clueless than their 12-year-old children about every single thing they have ever talked about.

This idea that older people know more is absurd. You spend 50 years passively ending up with knowledge, while someone else spends 5 years doing active learning. The 5 active years wins every time. Sure there's still some deep-thinking life lessons left to be learned, but that's like "don't let your emotions get the better of you" kind of stuff, not "I understand how this works".

It's like this dude at work. Thinks he knows everything because he's worked for 50 years and so he must have gained 25 times more knowledge and experience than the new young guy. No, see, what actually happened is he spent 50 years passively learning an average of 1 bare-minimum thing per year on accident when it was absolutely required in order to complete a specific task, and the young guy spends 8 hours a day actively learning and exploring knowledge-gaps because he's just damn interested in it and has learned more in the past month than the old guy has in 25 years. So now you've got this ancient anti-intellectual with seniority power (another stupid thing) overriding good decisions just because "that aint how we done it for 25 years damn kids think they know everything why the hell would we need a damn [...]"; and so they undo the thing and productivity drops back down to where it was 25 years ago.
