When people talk about colonialism being the thing which made so much of the world worse, let’s all remember that Afghanistan was never a victim of colonialism and it’s pretty much the worst country in the world.
Hong Kong
Singapore
Australia
USA
Canada
All the most successful countries started as English Colonies. Then look at the French colonies:
Vietnam
Lebanon
Cote D'Voire
Burkina Faso
Almost a level below in terms of quality of result.
At the bottom of the barrel, we had The Congo with the Belgians chopping off the locals hands as the default punishment for bad behaviour.
So the colonialist effect depends largely on the colonialists.
England - Good
France - Average
Belgium - Poor
Like the posters on this forum in a way.
