I see where you're coming from, but it's not really all that necessary if they're doing their part. That's like saying the owners of Macy's are doing a bad job because they don't personally visit each department store monthly or something. They have independent managers who manage the store and take care of all the little things. All the owners do is make sure the managers keep up to par with everything.
Everyone had different responsibilities that they each need to do and it isn't efficient if everyone is trying to all do the same thing.
