"this country had colonialism my country had colonialism. They can't keep using that excuse forever. This country is shit today because of the locals, they need to make it better instead of acting like they have no control over their own country."
I think comparing the colonialism of Malaysia and the Congo is incredibly idiotic. The Belgian Congo under Leopold is arguably one of the most harrowing examples of people in bondage in human history.
They really aren't even similar forms of colonization, which makes sense considering Malaysia was colonized nearly 300 years before Congo. Malaysia was also composed of a more uniform ethnic group, while the Congos borders were invented by colonizer states diving up the continent.
Most of the problems in Africa are a direct result of Europeans creating nation states with no regard to historical ethnic conflicts.
