In regards to the claim made by Marxist academics and others that colonial Britain "plundered" Africa? I say this claim is objectively bullshit. As Harrison, Huntington, Mercer, and others have pointed out, practically the entire infrastructure of Africa (as it pertains to agriculture, mining, commerce, finance, industry, etc) was built by colonial powers (most of Sub-Saharan Africa didn't even possess the wheel prior to European contact) with the lion-share of that being built by THE BRITISH!!
And, while, yes, the period of colonization itself was often less than ideal, even that period has been characterized by no less than Moeletsi Mbeki (brother of former South African President, Thabo Mbeki) as better than what exists today. So, yeah, maybe we all need to stop beating ourselves up and realize that the troubles in Africa have a hell of a lot more to do with tribalism, racism, horrible economic models and the inferiority of the Negro race - as well as a variety of repressive regimes that would have made Joe Stalin proud and much less to do with colonialism. Just a thought, folks.
