Simply put, any race that wants to have a say in this world must be a race with many babies! Poverty doesn't matter when it comes to the numbers of people.
Take China for example, a communist nation country with 1.2 billion people. Now you might think that the world superpower (usa) wouldn't want to do business with them because their ideology is one that they dislike but that would be their loss since their companies would lose 1.2 billion customers. You even have something General Motors plants in 'Communist' China. That's the economic connection.
Then there's also the connection of rule. 1 person nomatter how rich cannot rule over 10 poor ones, because that simply doesn't make sense. Therefore, for the West to stay in power they must try to control the population of the poorer nations, and promote their population growth.
There are more connections ofcourse but i won't get into that.
