Touching the title in a minute, "even when it means permitting them to bike in the rain." already gives a great insight into how utterly clueless she is about what's wrong with her.
*There is nothing wrong with having your child biking during rain.*
"But the kid could get wet and sick." Yeah, well, so what? Congratulations, you're experiencing Life. What if it doesn't get sick? What if this is actually great for the immune system? What if the kid's body "hardens up" a little and it won't get sick next time? Ever thought that through? No? Why?
Anyhow.
"it’s the Dutch social safety net that permits parents to feel safe and secure enough to allow their children this broad freedom and independence."
It is scary that the person who wrote that article actually has no fucking clue what a family is, what friends are, what the word community actually means.
She writes about stuff that used to be the norm and, in most of the rest of the world still is, as if she never experienced them, and ... she apparently didn't.
For the most part of my life, where i live, nobody cared about feeling safe and secure. That's just the obvious US bias she has, because she fucking doesn't.
To actively desire feeling safe and secure one has to live in fear. Where there is no fear, there is no need to desire feeling safe and secure. The whole idea is foreign.
Before the people of the US started living in constant fear, kids played outside. Kids were allowed to hurt themselves. Kids were allowed to play on the road.
People actually trusted each other. They trusted each other with their kids, too.
Anyways, this is all wrong. The happiest kids in the world are those who have parents that raise them with things like curiosity, integrity, dignity, respect, responsibility, a sense for self-improvement. You know, what people often refer to as "values". Sprinkled with actual empathy, instead of morals.
Instead, in the USm they raise their kids to become narcissistic, self entitled, insecure wannabes who care more about their opinions and ideology than about reality and the truth. They raise their kids to lie about literally everything, because an honest thought or feeling expressed towards someone might "hurt" them.
They raise their kids into believing they can do what they want, they can be what they want, they can get what they want, without ever teaching them how to actually know what they actually want and how to achieve what they want.
And how should they? Why should they? Where's the sense for self-improvement supposed to come from, when everyone's supposedly equal and the losers get Participation Trophies so they don't need to feel bad?
The one thing, feeling bad about losing, is literally one of the biggest drivers of self-improvement. "I want to be better than that" turns into a completely foreign idea when everyone constantly being told they're great and even the losers get Trophies anyway!
People with talents aren't talented, they're gifted. The idea, that someone actually might self-improve, is being removed in favour of the idea that one has literally nothing to do with it.
Anyhow!
"But what seems to be frustratingly glossed over in these case studies is the acknowledgment that it is an economic luxury to raise happy, confident kids who pay attention to the environment around them."
No. It fucking isn't. Again, not her fault, she has no clue.
Money doesn't raise good kids. Good parents raise good kids. Period.
It does not, in any way or form, have anything to do with economic luxury. Good parents raise good kids. Period. They can be poor and good parents, they can be rich and good parents. Asshole parents can be poor, or rich. Doesn't matter, they'll be assholes regardless.
Making "economic luxury" a requirement for raising good kids into good adults is greatly underlining that she has no fucking clue what the fuck she's actually talking about. I have little doubt that she never experienced actually good parents, never experienced being raised into a self-responsible, self-confident, self-improving personality and never experienced the base level of human normalcy most of the rest of the world has not yet actually forgotten.
And that's not only not her fault, it most likely also isn't her parents fault. Can't blame people for being raised into a fucked up, artificially created normalcy.
