>And they continue to be exploited.
Poverty isn't necessarily exploitation. The situation of Bangladesh would not be improved if every wealthier nation was suddenly sucked into the sea. In fact, the situation of Bangladesh would become considerably worse.
Bangladesh has grown rapidly by selling clothing to rich countries, and through the work of NGOs. Supposing we put a forcible stop to this "exploitation" by placing sanctions on Bangladesh, so no one can trade with it, and kicking out all of the NGOs. Bangladesh becomes much poorer.
>Colonialism benefited colonial nations, because of course it did. It wouldn't have been done if it wasn't beneficial.
According to an old European history textbook I read: Once you take into account the costs of conquest, infrastructure, and administration, plus the opportunity for colonial administrators to take a cut on the sly (since the monarch was thousands of miles away), colonies weren't profitable on net. Supposedly the Brits did colonialism first, and other European countries followed in Britain's footsteps because "that's what an industrialized nation does".
Do you believe Putin's invasion of Ukraine makes economic sense? I don't think that's what motivates him.
The invention of the map might be the deadliest invention in history. To paraphrase Carl Sagan: "Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could momentarily color a small additional part of their map with their nation's color."
>unprecedented improvement in material well-being in certain parts of the world, namely the colonizer nations
Compare a per capita GDP ranking of European countries:

With a ranking of the largest empires:
https://en.wikipedia.org/wiki/List_of_largest_empires
The top 10 per capita wealthiest countries in Europe, from Wikipedia, are: Luxembourg, Ireland, Norway, Switzerland, Denmark, the Netherlands, San Marino, Iceland, Belgium, Austria.
The top 10 largest European colonial empires, based on my skim, belonged to: Britain, Russia, Spain, France, Portugal, Turkey, Italy, Germany, Denmark, Belgium.
There's just not much of a relationship.
