I took home ec in 2001. I learned to use a sewing machine, it was great.

But none of the kitchen stuff we learned had anything to do with ensuring that this week's shopping list ensures that you'll get enough zinc next week, or the kind of prep that uses the other half of yesterday's cauliflower in tomorrow's dinner so that it doesn't go bad.

These aren't hard problems to solve if you've got time to plan, but they are hard to solve if you are currently at the grocery store and can't remember that you've got a half a cauliflower that needs an associated recipe.
