Sub-Saharan African households earn more than African-American households in the US.

African-Americans earn a median household income of 48,000 USD.

Sub-Saharan African families in the US earn a median household income of 58,000 USD.

There is not a single group in the US that earns a lower household median income than the African-American than the Native American.

Human sub-species are obviously real. It is just politically incorrect to mention them or be aware of them.

Medicine has different impact on Africans and White people but they are exactly the same.

My primary argument is that sub-Saharan Africans and Native Americans are separate sub-species from the rest of humanity, and that either the Sub-Saharan Africans will win the interspecies evolutionary conflict, or the rest of the human populations will.

The Native Americans lost the species struggle, and are nearly extinct now. Today, Native American alone makes up 1.1% of the US population and more worryingly, is rising in number.

Today, 12.4% of the US population identifies as black alone. This population is in decline suggesting that the Black sub-species is not successful in developed economies.

We see the fastest rise in the Asian sub-species in developed economies, which shows that the Asian sub-species is the most successful and adaptable sub-group when it comes to being part of the developed world.

As of now, the greatest conflict exists between the Sub-Saharan African subspecies and the rest of the world, because the Sub-Saharan populations are not able to intermix with the rest of the world's population successfully, and are thus left isolated and in a position where either their overrun a new territory with numbers, or are blocked off from the rest of the world.

The Sub-Saharan human also has a very fast reproductive rate, which makes his population grow far faster than the land can support him. He is also too dumb to build civilization by himself which places him in a position where the Sub-Saharan human can only ever succeed by spreading across Africa and beyond, but never by successfully growing his own land.

The moving to the rest of the world plan doesn't work however, as Sub-Saharan Africans are too divergent a sub-species group to be able to assimilate with the rest of the world. They have an extremely difficult time assimilating in North Africa, Europe, Asia, Oceania, North America, and even South America. To the point that they remain the least desired type of immigrant, besides middle easterners.

As of now, Sub-Saharan africa population doubles every 27 years, meanwhile their IQ remains around 66 in current year. Their current population density is around 40 people per sq km and would be 80 per sq km in 27 years from now.

With an IQ of 66, your economy GDP per capita would continue to decline as your population rises, as can already be seen in the case of countries like Nigeria, which have an iq 15+ higher than the average Sub-Saharan person.

At a 66 IQ, the people of the land are no longer compatible with developed economies. It is not just an issue of cultural differences, but the simple fact that they aren't smart enough to be able to process the rules that a developed economy is telling them to follow.

At 66 IQ immigrating your people to other places is a guaranteed net negative. It is an average IQ bad enough that only the top 1.1% of the population would be compatible with the developed world.

If you thought trying to assimilate Syrian refugees was bad, imagine how much worse trying to assimilate people with an IQ 10 points lower than that would be. That's how low it is.

In conclusion, Sub-Saharan African sub-species of humans are not compatible with any other society on Earth, and could at best have the top 1% of their populations assimilate with other populations. This leaves a 99% populaiton that will never become rich enough to stop reproducing. That will overpopulate their region and would either suffer constant famines or genocides perpetuated upon them by themselves in a bid to survive the overpopulation issue.

In Rwanda the genocides already occurred because of this, and in the future we can expect more similar genocides to occur across Africa, as their domestic populations overpopulate without having the intelligence to create systems advanced enough to administer such large and densely packed populations.

Rwanda's population is expected to double once again in 30 years. With a current population density of 535 per sq km, it all but guarantees another Rwandan genocide/ war breaking out within the next 30 years.

Another similar example can be found in Bangladesh. Where with a population density of 1165, they end up in a position where they have to begin attacking minority populations in the country to get anywhere further.

Africa will eat itself alive. Until only one single African sub-species dominates. After that Africa will fight the rest of human civilization, and only one will come out on top.

Who is most likely to win?

It appears that Africans might end up being the future of humanity as they are the only sub-species of humans with a consistently high fertility rate, while the rest of humanity is falling below replacement levels. It this trend holds, then the Africans will have replaced the rest of humanity similarly to how we replaced the Neanderthals.

Unless we kill them all first.

Conclusion:

Humanity is going to genocide Africa. Zero question about it. As it cannot win the replacement game, it will simply genocide Africa instead to win. China isn't going to repeat the west's mistake of going but they are just like us its okay if our streets are filled with brown people with zero relation to us in 60 years. China isn't going to do that. Genetics is your inheritance. The west throws it away. They lost.

The final race war will be between Asians and Black people. Asians will win because they have a 35 IQ advantage with a higher or at worst equal population. That 35 IQ difference is the equivalent of modern day Chinese fighting against 1850s white people. You know the 1850s white people aren't winning that one.

The Chinese are going to end up mass sterilizing the African population. Bottom 50% every single generation. They will keep doing this until the African population reaches a comparatively ideal size and IQ. Then the Chinese will write history books in Africa about how the Chinese uplifted their populations and saved them.
