The big thing about Western colonialism, leading to the great social mess in South Africa, is that the West is eternally guilty. The Left have this as one of their “big things,” but they go to sleep when their communist mummy China does the exploiting. The extent of this exploitation in Africa is staggering, as Doug Casey claims:

“Justin: Is China exploiting Africa? Doug: Of course “exploit” is a loaded word; it implies one-sided, unbalanced dealings, and unfair business—although the word “fair” also has lots of baggage, and politically charged meanings. But, yes, they’re definitely exploiting Africa. We’re seeing a veritable re-colonization of Africa. Every time I visit Africa I see more and more Chinese. It doesn’t matter which country; they’re everywhere. It’s important to remember that Africa doesn’t produce anything besides raw materials. There’s close to zero manufacturing, like 1% of the world’s total, in sub-Saharan Africa. And almost all of that is in South Africa. The little there is, is only produced with the help foreigners—Europeans, but increasingly the Chinese. … The Chinese see the place the way the Spanish saw Mexico and Peru in the 16th C. Of course they won’t say that in public. In fact it’s very non-PC for anyone to make that observation…

Nonetheless, Africa is going to be the epicenter of what’s happening in the world for years to come. It’s gone from being just an empty space on the map in the 19th C, to a bunch of backwater colonies in the 20th C, to a bunch of failed states that people are only vaguely aware of today. Soon, however, it will be frontpage news. And this is both because Chinese are moving to Africa in record numbers and Africans are leaving as fast as they can. I read something a few years ago about how China wanted to move 200 or 300 million of its citizens to Africa. Most people aren’t aware of this. It hasn’t been widely promoted, but this is another trend. Rich Chinese are smart to diversify to developed Western countries. Poor Chinese go to backward countries, to try to become wealthy. Africa is the prime recipient. One reason is because China is lending scores of billions to backward countries, mostly for infrastructure development. But the roads, ports, railroads, and what-have-you are built almost exclusively by Chinese companies with Chinese labor, who stay there. The infrastructure is there to enable the export of raw materials, mainly back to China. But the debt has to be repaid. It’s a great deal for China.

It will be interesting to see what happens when a couple hundred million Chinese are living with a radically expanding native African population. Few people realize this. I ask knowledgeable people what they think the biggest cities in the world will be at the turn of the next century. And they all guess cities in China or India. But that’s not true. Eighty years from now, Lagos, Nigeria will be the largest city in the world. It’s on track to have a population of more than 90 million. The world’s second biggest city will be Kinshasa in the Congo with about 80 million people. Dar es Salaam of Tanzania will be the world’s third biggest city with a population of roughly 75 million people.”

     If this is so, then it is important to ask where are the resources to support this growth going to come from? If Lagos, Nigeria, does reach a population of 90 million, as projected, how will this quantity of humans be sustained? These questions because of political correctness are not being asked. But, if no solution is given, it will be the African people who suffer when their societies implode. That will be a worse fate than any nice liberal  dinner table discourse on racism and colonialism. In the end, what really counts are peoples’ lives.
