I wish I could remember the title but there was a book written that tracked aid to Africa since WW2 ended. It might have been written 10 years ago. Almost all aid is stolen by African govts. The conclusion was that over a trillion dollars have been sent to Africa and every bit of it is wasted. Achieved absolutely nothing.
Also all aid through NGOs is wasted. Most NGO “aid” is used to pay NGO staff. The only aid organizations that actually help people there are Church missions providing medical care, etc. UNICEF and CARE, etc are scams.
