Got to love calvinist societies like northern europe. "oh you are poorer than me due to centuries of colonization? That's your own moral failing!".
And while nowadays they are mostly non religious and don't directly express the idea in these terms, the disparity of treatment is still incredibly strong.
And basically it's all down to having better weapons at a certain point in history.
If only the protestant countries' secret services would stop arming rebels every time they democratically elect someone that wants to stop funneling riches to said protestant countries…
