I assume that Stacey Dooley was chosen both because of her cekebrity status following Strictly and because of her experience reporting on controversial matters in other countries. She has admitted herself to being uneducated but is fearless in meeting people and probing issues that many would prefer to see swept under the carpet. I know from experience that if you are in rural Africa local people - even adult ladies and especially children, will come up to a white woman, and touch their skin and hair out of curiosity. Children may beg be be picked up. Of course they may not be above hoping for something in return - biro pens are much sought after.
Yes corruption is rife and the future may see these countries further impoverished by being in thrall to the Chinese who have lent them the means to modernise way beyond their ability to repay, and in return for access to mineral resources, but had the original colonialists not plundered these countries in the first place, and had they educated and taught them how to rule, things might have developed differently. The locals saw the lifestyle of the white rulers and thought they could all have the same, but have been unable to elicit the necessary skill and labour from the worforce to support it. Enter the Chinese - who as often as not, bring in their own workforce as little more than slave labour.
