Am of the view that these Economies will not have any meaningful economic progress until they deal with the problem of corruption in their countries because looking at these developing Economies most of them are very blessed with mineral and human resources but what is the problem that they can't even afford their citizens with the basic necessities that they need such as good road's, electricity, access to quality health care system and a access to quality education system.
Until corruption is done away these Economies will continue to be puppies in the world
Corruption could crippled the economy of certain country and until there's a leader that is so greedy to grab the resources of their country then there's no growth to expect from these officials.
We know how bad the economic state of those countries stated here and I don't know on why these corrupt people still not been eliminated in their seats since we have now social medias where everyone can express their opinion and the would know the real situation on their country. If they keep voting those people who's not for people and for growth of their country then expect that no changes will happen. But if they start to wake up and find those good people who's aim to change the status of those countries then maybe there's a good chance that they could see some developments.
