We don't have cooking/repairing classes either, I guess they sound a bit too old-fashioned. Who wants to be the one doing the cooking and repairing, you should be learning useful things to have a high-salary job which allows you to pay other people to do the cooking and repairing for you!
And so our obsession with degrees leaves us with more helpless generations.
We do have sex ed though - but mainly because teenagers nowadays learn it all wrong from pornography, and unless someone tells them that's not normal sex they do believe they should be reproducing the kind of weird stuff they watch.
As a teacher I've always found amusing that parents often focus on what their children are worse at instead of what they are best at.
If a children is good at art and bad at maths, maybe you should provide further art education instead of trying to keep them away from arts and force them to learn maths - but usually parents think otherwise.
Because, again, following a fixed path seems to lead to "useful" results.
