The “resource curse” is just people trying to pretend imperialism isn’t responsible. Norway has plenty of oil and they have a high quality of life, because nobody invaded them.

Plenty of these countries had leaders who wanted to use their resources to help the people, but the powers that be, most often the US, didn’t want that. And so for example Mohammed Mossadegh of Iran, a peaceful, democratically elected progressive, was overthrown by the CIA, and he was replaced by a monarch who could be easily bribed and would use the oil to enrich himself. And when that monarch caved to domestic pressure and participated in an oil embargo, US support was withdrawn and he was overthrown and the current government came to power.

There’s no “mystery” or “curse.” It’s just imperialism. The story generally goes that these resources were stolen by force during colonialism and remained in foreign hands after independence and the country still functions as a neocolony, leading to poverty and exploitation, or war and instability if they challenge it.
