Children ARE, a reflection of their Parents. The old adage of "no bad kids, just bad parents" is very true. They learn from a VERY early age, how to behave from those around them....we all pay the price for a Parental failure to teach a child to live in the world as a decent human being, and let the TV/internet/street do it for them, or rely on others, because the fact is, most humans who have children, do not have the ability to raise them. An ability is not a right, even when it comes to breeding humans.

99% of everything on the Internet is crud because it lacks the educated filtering of professional peer groups...

If you've ever been involved in the peer review process you probably don't have much confidence in the process. The way that personalities, academic rivalries, turf battles, good ole boy networks, tit for tat recommendations or rejections, etc., impact the process makes it just as suspect as anything else you read.

I believe you're thinking of "Sturgeon's Law", after sci-fi author Theodore Sturgeon.

...the teachers and lecturers in schools and universities have done the sifting already and so present to you what they have found to be important.

You're right, of course, but what educators have found to be important has been sifted thru the filters of their own bias, and that of their instructors in turn. I suppose this is just human nature and is to be expected. The internet exposes learners to every sort of bias and thereby forces them to construct their own filters, if they're capable of doing so.

It is a problem that many people are dwelling solely in their special field of expertise and that they cannot see beyond their own nose.

I know this guy who does research on growing hybrid poplars for celluosic biofuel conversion in a semiarid region where the soil pH is 8.2 and the mean annual precip is 8.2". He utilizes computer controlled solenoid valve irrigation and knows precisely what micronutrient supplementation the trees require. I would imagine that he's the world's foremost expert on growing poplars under conditions they aren't adapted to. Yet there is no market for his trees, which I call his "bananas in Alaska." Has he ever asked himself WHY he thinks he needs to grow these trees that nobody wants where they don't belong? The reason he does it is that there's grant $$$ available for cellulosic biofuels research. To him, this is more than sufficient justification for this waste of the taxpayers' $$$.

So far the establishing of a critical mind is not only neglected, it is even discouraged. And that is, maybe, the point, where the school system really fails.

In the first place, few students possess the intellect to support critical thinking. For the few capable of developing critical thinking skills, the schools are designed to ensure that they never do. If large numbers of citizens ever developed critical thinking skills, the status quo would collapse. Everything from politics & religion to organized sports would be seen for the scams they are. The powers that be can't allow that. And for the very few who are capable of developing critical thinking skills in spite of the organized childhood long attempt to prevent them from doing so... well, here we are. :)

I think that dissecting animals is one of the more valuable things that kids do in school. For really learning how animals function there's no better way to teach it. A computer simulation doesn't give you the same feel or the same experience of discovery as actually dissecting an animal. This isn't only knowledge that is valuable to kids destined to become surgeons, doctors, nurses and veterinarians. Dissecting animals also provides experience with the scientific method. These are things that are much harder to teach solely from books and simulations.

Except that dealing with your peer clique is a lot of what most jobs are about.
It would appear likely that many homeschooled people may be seriously lacking in this respect.

Well that sounds like a good start! Maybe homeschooling will save the world from the emptiness of 'networking' and being a 'team player'?
