The reason why rich, especially british, american and swedish for example, alm being genetically close to each other, wasnt higher intelligence. In fact they have been much lower in intelligence than the nations that lived in harsh enviroments in the north. Living in easier enviroments, they were always able to reproduce much faster than nations living in harsh enviroments in the north. They have also been very psychopathic, dishonest, deceptful, narcistic, vicious and aggressive

Similarly to reproducing much faster, their secret wasnt never higher intelligence, but reproducing much faster, as well as in case of british, american and swedish, they produced factories, against which much higher in intelligence, but still living in harsh enviroments couldnt compete against. Also, these other very naive, honest and too kind northern nations were as if disarmed against very dishonest, vicious and aggressive southern states. Because of high narcism and psychopathic traits and living in easy enviroments, these nations got the impression that these are somehow better, more intelligent people. Facts speak for themselves. In fact they were always bunch of narcistic and psychopathic idiots full of themselves.

Average american soldier has IQ of about 83-85, while they have been invading and occupying much more intelligent nations, thanks to the easy enviroment allowing developing less meaningful things, as well as private money machine. To this day, they are still trying to boss around much more intelligent chinese and japanese. Japanese were enslaved by american and british by mass murdering japanese civilian Island by Island, when they burned everything to the ground and after dropping 2 nuclear bombs purely ti civilian targets. Same with Vietnam, Germany (Dresden etc. being worst example) and Korea.

American and british do not want their slaves and vassals to know the real history and truth. Otherwise they couldnt virtue signal being the moral beacon of the world, which you can keep seeing with the Ukraine war, Russia etc. Oh, they are so moral, so good, so much better people.
