Being a tailor, and learning how to sew never interested me. However I do know how to use a whetstone (known to most as a sharpening stone), and I am a very proficient cook. I'm not an expert by any stretch of the imagination, but I can outpace most people when it comes to making a quality meal.
The problem is that parents aren't expected to pass these skills down. In fact they're encouraged not to so that the schools can teach their kids everything. The problem is that these skills aren't taught in any required classes, which is where the flaw in our society becomes apparent. Not knowing how to sharpen knives, and how to cook a decent meal is actually quite distressing (in my mind), because if you can't cook properly, then you won't be able to survive on your own for very long.
I never learned how to sew because my hands are too big, so it's impossible for me to thread a needle effectively. In fact I find it quite frustrating, so I just left the sewing to my mother, who learned it from her adoptive parents (we don't know who here biological parents were, because she never knew them to begin with).
In short, I agree, it worries me that people aren't growing up with basic survival, and domestic skills. However, it isn't up to us what people do and do not learn, and what may seem simple to us, could quite possibly be an impossible task for someone else. I mean, how many people do you know who could perform surgery?
