A political appointee who doesn't know the job, huh? Fancy that. At least he didn't just waltz in through the public/private revolving door.
I agree with him, though. Running an organization requires a set of skills different from, and not necessarily a superset of, the skills of lower level workers. He does not need to know the low-level stuff, that is not part of his job description.
Whether or not he does the job well will depend on whether he listens to the people below and around him and gives proper weight to their ideas and recommendations, or if he tries to impose his own agenda on everything he touches, the way that many (most?) political appointees do.
