Some people love to hate Slytherin and all it represents. Yet Slytherin is an archetypal necessity that possesses tremendous merit.
Without competition the world would stagnate. Knowledge (Ravenclaw) and kindness (Hufflepuff) are both wonderful, but very localized. What can you do with knowledge if there isn’t an ambitious Slytherin broadcasting it? It just dies with you.
How do you get great ideas out in to the public eye? You think the world just lets that happen? No. Galileo and Jesus’s head are always on the chopping block.
Ravenclaws can yap about knowledge but, when push comes to shove, it’s a Slytherin who is going to take their ideas and actually change the world with them. Hufflepuffs can be sweet and nice but when push comes to shove its Gryffindors fighting the war up at the front line to defend them. Otherwise it’s all North Korea and the rich powerful run everything.
You may not assume the Slytherin would want to broadcast your kindness and knowledge, but understand, that’s what Slytherins do to get ahead. They take something that people need so that they buy it and thus they get paid.
Slytherins are shit heads, but they are necessary for the world. They may be broadcasting an idea because they want to make money or be famous. But they’re still selling it. While Hufflepuffs are resisting competition because they don’t want to hurt anyone, Harry Potters, Hermiones and Snapes are up front and center defending and fighting for what they believe. Rowling is a Hufflepuff herself, but her book centered on Slytherins and Gryffindors for a reason: because thats where the world moves.
Still, Hufflepuffs are equally necessary to the world, because kindness is a thing worth defending. If that doesn’t exist, Gryffindors will go back to sleep and Slytherins will take over.
I am a thousand percent Gryffindor. I’ve always been ambitious, but my big heart defending what I believe is first and foremost and I’ll die in the fire of my loyalty and integrity. If there’s one thing that stops me from “making it big” it’s my big stupid heart. I work hard, but I won’t sell a lie. That is the death of me. And it can be stupid, but it’s the way I’m wired. Still, I’m smart enough to recognize that without Slytherins, people like me would have no purpose and nothing in society would move.
This is not to say that (archetypal) Hufflepuffs utterly and completely lack ambition, but rather, that they are under the delusion that they don’t have to step on any toes to actualize it.
