Kids need to be educated because knowing a bunch of stuff about the world is the greatest gift we can give them, and it needs to be given while they are still young enough to appreciate it. You can't live a full life without knowing a fair amount about all there is to know, and you can't experience things without having some context.
Knowing only things that are economically useful will still leave you in a place where you wonder how the world works, and wondering why there's a hole in your soul.
