Because Kikes.

It's a feature of the universe. A few details:

1) Our universe is computable. All this means is that there is cause and effect. The moment you have cause and effect is the moment everything is computable. So, for example, if you play pool, every shot has a cause and effect. If you know just enough variables of the last shot, you can compute the exact position of every billiard ball at the start of the game.

In other words, cause and effect in the universe just means you can derive math and logic rules out of the universe and write them down to figure stuff out.

2) The moment you can derive math and logic rules for your universe is the moment you can start arranging them in ways that create algorythms.

Algos are just logic + math rules arranged in arbitrary ways that have unique behaviours.

One the one scale, you can see algorythms everywhere, including the machinery that creates and maintains our dna as well as the microbe soup that we swim in.

On the other scale, you can create robot swarms controlled by algorythms behave in all kinds of interesting ways. One of those interesting ways is that robot swarms that are in competition with each other will often be found to "LIE" to their competition to gain advantage and score points to win a game. I don't have the link, but there are documented robot swarm experiments where over time one swarm will eventually evolve behaviours that look like they are LYING to their competitors to gain and advantage and win points in the game that were set out for them.

3) What this means basically is that the universe has a built in property for algorithmic machines: if it costs less energy to lie or trick your opponent rather than competing fairly, those that lie and trick will win more games.

4) But it gets a bit more complicated that that. Game Theory. Game Theory is the idea that there are different types of transactions available between individuals (algorythmic machines) and that you can play games with the participants to see the typical outcomes. Here is a link to a short online game that explains game theory and runs through simulations to show you when liars win / draw / lose: https://ncase.me/trust/

5) Now, there is a problem with the game I linked to. The game assumes that all humans all around the world are the same. This is wrong. We have at least 7 species of humans around the world that are unique and distinct: white, black, shitskin, chink, southeast asian, aboriginie, north american indian. The reason that game is flawed is that each of these 7 species of humans have been playing game theory every single day of every single generation of each of their species since the beginning of time. What this means is that each species has embedded within its genome a "PREDISPOSITION" towards a specfic balance in the game theory strategies. So, for example, we find that whites are PATHOLOGICALLY VIRTUOUS to the point that they will kill their own children to save another group. Our evolutionary history of living in harsh environments has embeded in our genome a predisposition towards severe co-operation and self sacrifice. Niggers, on the other hand, they are a trickster species. If you have ever dealt with blacks extensively, you will find that they lie all the time because in their evolutionary environment it took less energy to lie, cheat and steal something for survival and embedded that in their genome.

And so on. All human species have these kinds of biases hard coded into their genome.

So, to your question:

5) You are asking your question from the perspective of a white man, which means you are basically asking this question: Why aren't other human species as pathologically virtuous as white people?

That is basically what your question translates to.

The answer is because the universe embedded into our genome and those of our competing human species different biases towards different game theory stragies realtive to the needs of each of those species to survive.

6) But, it is interesting how your question answers a few more questions. Why is miscagenation wrong? Because, not only does the leaf now fall off of the ancient evolutionary branch of your people instead of extend it, you have now created a hybrid with god knows what kind of evolutionary bias mix in their genome. Miscagenation simultaneously cuts you off from your own people and destroys the inbuilt evolutionary wisdom embedded in your genome.

// EDIT: Also, the universe has other properties like friction and a tendency towards disorder. Not only are there evolutionary pressures embedding data into our genome, the evolutionary process it self goes through the friction + entropy filters, which just means the data evolution writes and copies into our genome is NOT PERFECT. There are always errors, so the evolutionary pressures + the natural accumulation of errors biases every single algorythmic system over time into it's own unique direction. There is no escaping this in any natural process.

It also answers questions like, why do black people and jews lie, cheat and steal everything BUT their lying, cheating and stealing strategies are COMPLETELY different. Blacks are short term, low impulse thinkers and their tricksterism is always a grift for how much cash can they get to get them by for a day or two. Jews, on the other hand, play a high level sophisticated type of tricksterism that is kind of like a chinese finger trap, they re-arrange words and concepts to entrap their host population in perpetual mind games out of which most of them can't get out.

It also answers why abos, shitskins, chinky chinks, south east asians and all the other groups are the way they are no matter how many generations their kids spend within foreign populations.

Great question.
