Actually, here they acknowledge that weak and ineffective government is the thing holding those countries back economically. Of course, the reason for this is (neo)colonialism (murdering anyone who even hints at nationalisation of resources).
It's funny how capitalists say one thing, but when their money is on the line they know exactly how economics actually work.
Even without there being an obvious explanation that analysis is so empty "why are they poor" "they lack properties of a wealthy economy" like fucking duh. How do you plan on instituting all this state infrastructure in a resource starved country?
economists will be like "the third world doesn't understand Basic Economic Management Theory" and they're literally just talking about The Secret and the pbs series where milton friedman explains that pencils are made in factories.
Property rights are insecure and very inefficiently organized, markets do not function well, states are weak and political systems [do] not provide public goods.

Economics always side steps these issues. Oh, you see, it is the Dutch curse, resource rich countries are always doomed to become reliant on volatile commodities, no I will not elaborate, no, I don't know anything about CIA intervention, IMF debt traps or colonial legacy. This is what no historical materialism does to a motherfucker.
