It’s probably an accurate observation that relations with the United States and other developed nations haven’t helped the undeveloped nations as much as people might have hoped. This is especially true in Africa.
The real reason for this is HBD. When the average IQ of an African country is 80 or so, there’s no way that any amount of economic development is going to lift up that country to the same level as the United States or a country in Western Europe.
The anti-neo-colonialists deny the truth of HBD, so their explanation for the failure of business relationships with the U.S. to help undeveloped nations is that the United States is evil. This is similar to the way that the educational achievement gap in the United States is blamed on racism. In both cases, there is some sort of evilness perpetrated by white people that’s keeping the non-white people down. Except for Asians, of course. Neo-colonialism hasn’t hurt Singapore.
Anti-neo-colonialism is off the radar for most people, but not for Obama who spent several years of his early childhood in Indonesia and who has idolized his Kenyan natural father.
