>I wouldn't be surprised if that is the case with other former colonies of Europe.

In Latin America, the central extractivist structure was kept after independence, only the owners changed. Now instead of a foreign crown siphoning off the wealth, it was the local owners of the land -- who still sold as much as they could to foreign powers, and spent the rest in petty civil wars against their own people. Another common occurrence was involving foreign powers in local disputes, as the landowners always put their own interests before the interests of the country.

Nowadays it's less overt in most places, but it's still going on.
