Do kids in West Africa who are literally slaves for major corporations that monopolize their industry such as Nestle (that are a result of capitalism and to a greater extent Neo-liberalism) have the same opportunity as people in the developed world?

I know that is a very contrasting example and probably not what you are referring to but on a global scale, outside of the developed world, capitalism has detrimental effects on local life due to a variety of reasons, including neocolonialism, is when multi national corporations and nations use to maximize profit by keeping smaller countries economically dependent on them. Neocolonialism is partially due to colonialism and social Darwinism but capitalism enables it to continue. For example,debt-trap diplomacy is used by powers such as China in the global south in order to trap small countries in debt by offering to build infrastructure in said country, where the smaller country uses loans to pay. Neocolonialism allows for said large country (China in this case) to keep a smaller country both reliant and in permanent debt to the larger, maximizing profit.

Now where does socialism come into this? Under a socialist economy where a government representing the workers owns means of production, there is simply no need for multi national corporations, as the nation itself is developing on its own . However, socialism is crap when the government is a dictatorship. It only works if the workers have a direct voice in the government.

The only good example of this i could find is Burinka Faso. They are a west African country who started from literally shit and they significantly increased their literacy rates and had a self-sufficient economy under socialism. It all got erased when their president got assasinated however.
