"And that question is part of the problem." Draco frowned. "I got Hagrid fired as Care of Magical Creatures teacher and I'd do it again even if not as pettily. But there's no reason Hagrid couldn't be a great teacher. He's got the knowledge and certainly has the passion. He just hasn't a clue about classroom safety or how to teach. Both of which can be taught."

"And that's the problem." Draco's tone was dry. "Binns needs to go and the Muggle Studies teacher needs to be a Muggle and to teach about the Muggle world as it is now rather than the one when Dumbledore was young. But those are symptoms. The systems are broken. Teachers aren't taught to teach, which can work but didn't for Snape, Hagrid, or most of the Dark Arts teachers."

He reached for his tea. "Good systems do well with average people. Bad systems prevent good people doing a good job. And right now Hogwarts is broken to the point that no one at Hogwarts has a clue why you'd put the most ambitious all into one house and then not get evil wizard after evil wizard. Or even what a Dark Lord actually is. For that matter Slytherin is so broken right now that almost all decent wizards and witches ask the Sorting Hat not to put them there. So you get the toxic swamp which I fed while I was here."
