“...... Pointless arguments?"

Grindelwald's brows twitched, and he subconsciously repeated.

On the other side, Dumbledore also looked at Elena with interest, and there was a hint of inquiry in his eyes.

"Yes, it's nothing more than a paradoxical variant of consequential justice and procedural justice. This is not an uncommon thing in the non-magical world, but it can only be said that you know too little about Muggle law and philosophy. ”

Elena replied nonchalantly as she planted the soft-shell crab legs in her hand by the campfire in turn.

There is no doubt that both Dumbledore and Grindelwald hope to influence and change the world through their words and deeds, but the two have completely different definitions in terms of logical cause and effect, as well as emphasis.

If Dumbledore was a staunch guardian of reform, advocating gentle, orderly, and orderly social progress, then Grindelwald was an absolute revolutionary forerunner, but everything that can achieve justice is a worthy sacrifice, otherwise it is a waste of human social resources.

As has been the case in the non-magical world for countless years, in the eyes of the vast majority of people, these two issues are an either/or, completely irreconcilable twin paradox......

"You mean it's a paradox that can't be answered, right?"

Dumbledore smiled slightly, looked at Elena gently, and nodded thoughtfully.

"That's right, sometimes people want to follow the shelter of order, and when order becomes the injustice itself, people will seek true justice, so ......"

"So, why can't you find a balance that satisfies both?"

Elena sighed, turned her head to look at Dumbledore, and asked in a calm tone.

"If a thing can be carried out in a state of order and can achieve the desired result, does it not satisfy the demands of these two points of view at the same time? ”

"You're still naïve, kid. ”

Grindelwald grinned, stroked Elena's hair, and shook his head.

"In reality, it's never as perfect as you think it is, and most of the time you'll have to face a choice, either compromise in the process or compromise on the outcome – things that are happy for all exist only in the imagination of theory. ”

"Muggles are multiple-choice ......"

The corners of Elena's mouth lifted slightly, and she drew her wand and stabbed at the bonfire in front of her, and a fiery snake leaped high.

"We are wizards. Besides—isn't that what magic is all about when imagination comes to life?"

"Huh?" Grindelwald frowned, a little confused.

"Everything in this world, magic, wealth, power, food...... All of them have a price, which means that as long as there is reasonable negotiation and cooperation, we will be able to find a balance that meets the value needs of both parties to the transaction. ”

Elena glanced at Grindelwald, then at Dumbledore, who was also puzzled, and smiled slightly.

"To give a very simple example, potatoes, food, magic, students. ”

"In my opinion, most of the contradictions come down to a lack of resources – which could be wealth, food, spouses...... Even such intangible existence as honor, status, and longevity. ”

"Whether it is the magical world, or the non-magical world, whether it is human society or the natural biosphere, all beings who live in this world are more or less bound by [equivalent exchange]. ”

"However, the existence of magic can completely transcend the shackles of real equivalent exchange and create a high premium. ”

In other words......"

Elena said with a sweet smile as she handed two crunchy soft-shell crab legs to the two old men.

"With the help of magic, we can give anyone a big chip that's hard to refuse. ”

In game theory, there is an important concept called Pareto optimality, which is the ideal form of economic distribution that almost all master's students in economics will come into contact with, and Elena, who stumbled and got her diploma in her previous life, is no exception.

Pareto optimality refers to an ideal state of resource allocation.

That is, assuming that an inherent group of people and allocable resources, in the change from one state of distribution to another, makes at least one person better without making any one person worse off, in an absolute ideal model, it will achieve an extremely fair and efficient system of distribution of social cooperation.

In practice, however, it is difficult to make one party better out of thin air without harming the interests of the other party – with a sufficiently large sample collection, there will always be a related party that takes on the role of the exploited.

Unless......

"On the premise of a sufficient premium, the win-win outcome will be formed at the beginning of all events, and then regress according to this result, replacing the possible damage to interests in the middle, or the sacrifice link, with magic. ”

Elena picked up a clean-eaten crab leg and drew lines and circles on the loose dirt floor.

As a top student of economics, it is not too difficult to explain this most basic theoretical model to two old wizards, even if it has not been paved with too many basic theories, combined with graphics and cases, it can be roughly explained.

"This can be exemplified by Gryffindor House...... In the normal non-magical trading market, Gryffindor that only grows potatoes as the [base currency] is equivalent to an exploited labor force at the bottom. However, due to the fact that magic can produce a blowout of potato yields in a short period of time, they are the dominant side. ”

"However, as far as I know, Gryffindor House has not had any advantages since the new rules were enacted......"

Dumbledore pushed his glasses with his left hand, interrupting in some confusion.

"That's because they lack the most important way of thinking. ”

Elena spread her hands and turned to look at Dumbledore, explaining without thinking.

"Gryffindor, which has the largest potato reserves and productivity, can always have a say in the market by reducing and expanding the amount of potatoes in circulation in the market – and this is the most powerful weapon I have left them. In the same way, the other three houses also have their own advantages, all of which are regulated by introducing the variable of magic. ”

"Actually, Professor Dumbledore probably knows best, isn't it all sitting quietly in the potato warehouse under the castle, waiting for us to use it for the next step? ”

"But ......"

Dumbledore frowned, rubbing his temples with some difficulty.

Although Elena said some very simple sentences, but for some reason, when he understood it together, he always felt a little pain in his head, which was a strange way of thinking that he had never seen before.

"Don't worry about ......"

Elena's eyes gradually brightened, and she shook her head triumphantly, and the crab leg in her hand swiped on the ground.

"Next, I'll break it down for you briefly, which can actually be demonstrated by a very simple and intuitive quantitative economic model, first of all, we will set the demand group into several sets ......"

"Wait!

Before Elena could finish speaking, Grindelwald suddenly interrupted in a hurry.

"Huh?" Elena looked at the old man in front of her, tilting her head rather cutely, "That, grandpa, is there anything you didn't understand about what you said before? ”

"It's not a problem that I don't understand somewhere, it's, it's, hmm......"

Grindelwald glanced at the large array of enchantment-like formulas and lines on the ground, took a deep breath, and tried to get rid of the vague vertigo that lingered in his mind.

"I believe there is some truth to what you say. Indeed, if you use magic flexibly, you can avoid many of the arguments and sacrifices that we have encountered, but there is one thing you didn't consider!"

"Which point?"

"All of this needs to be based on effective communication. ”

Grindelwald drew his arms in the air, looking at Elena with a scrutinizing look.

"Perhaps, according to you, after negotiation and getting to know each other, there is always a balance between the two sides who disagree somewhere, but you first have to get them to sit together calmly and discuss......"

"That's right, it's like it's hard to get a Death Eater and a Ministry of Magic official to sit down and discuss a way to resolve the conflict amicably. In many cases, if you can really communicate well, there will be no conflicts. ”

Dumbledore nodded approvingly, a look of embarrassment on his face.

Neither Dumbledore nor Grindelwald had thought of such a way.

Even if there is no inscrutable premium trade, or some kind of Parker's law, people will think of solving the problem through communication - because of the method, regardless of whether it is successful or not, many times it is not even possible to communicate.

Elena glanced at Grindelwald and Dumbledore, pursed her lips, and replied rather lightly.

"You talk about this problem, but it's not a problem anymore. Don't forget, I'm not the same as the two of you you were dealing with now, and different times have different ways of dealing with them. ”

"Huh?"

"I don't see any difference between people. ”

The two old wizards glanced at each other, and the confusion in their eyes became more and more obvious.

"It's simple. Isn't that obvious?"

The little hair on Elena's head shook proudly, and she said confidently.

"I have your backing now!"

Dumbledore:......

Grindelwald: ......
