the culture predominant in Africa does not led itself toward economic progress
Yes this is exactly right. Its all in the culture. Westerners happened to stumble upon a set of values that are conducive to wealth creation while the africans have, for various reasons, not developed these sorts of values. The values that africans have are actually sort of noble, its not for lack of morality or anything like that, its unfortunate that the right values for wealth creation are so unintuitive.
It wasn't happenstance. Westerners' good set of values wasn't happenstance. Westerners' intelligence is waning. It is evident in the following.
The Spark that Westerners were intelligent enough to see was the Bible. The Bible, along with their natural position of intelligence, gave them the wealth that they have. It works something like this.
Westerners are generally low enough of intelligence that they need certain superstition. They are high enough of intelligence that they need logic at the same time.
Other groups, like the Eastern Asia groups, have the higher intelligence, but their very intelligent leaders of the past imposed such strong superstition on them (to control and enslave them), that though they are generally more intelligent, they have a lot more superstition to work through to get to the logic. Superstition that is passed down from parents to children is very hard to break.
Other groups, like certain of the Africans, or certain of the American Indians, have a low enough intelligence that makes it difficult for anyone to "push" them into strong superstition (because they are not intelligent enough to understand the depths to which superstition can go), yet they have reasonable enough intelligence so that they can live well in the more primitive ways.
Because of the above, God saw that if He could get the Westerners moving in His direction, they would be just the right group to break through the superstition and spread His Word of salvation around the world. This is what is happening. Those stupid Westerners are being used by God to spread His Word and salvation around the world, and few of them even realize it.
Part of the way that God is doing this is to allow blessings to come on the Westerners. The blessings include technological advances, the technological advances that allow them to have worldwide communications and transportation.
The problem with the Westerners is that, at the same time some of them are using the technology to spread God's Word, others of them are using technology to alienate themselves from the God that saves them and Who gives them their special blessings.
God is very smart. He doesn't need Westerners to spread His Word around the world. He can find other ways. If the Westerners won't get back into believing in God, and if they won't stop simply destroying other nations for the enjoyment of destroying and conquering, they, themselves, will be destroyed by the same God that built them up. God will find other ways. Because of Westerners' waning intelligence, they are gradually failing to recognize that it is God that is blessing them.
