I think you missed my point a bit.
The point is when people have to buy something there is a presumption that someone other than them is making money and it has been the experience of many that persons come peddling products packaged for particular ethnic groups but after the sales the people are left alone to deal with their day-to-day problems.

It does not make a difference if they ask who is making money or if it is for a good cause. They are used to lies in sales pitches. Few will investigate but most go with experience. If they do not see immediate benefits they will not take you seriously.

They will buy Nike sneakers because that gives peer status (short-term satisfaction) but for something as illusive as the future they are wary.
My point is if one is helping one have to consider the reality of the people to be helped. An African recently from the continent may purchase to deal with ‘homesickness’; it does not necessarily mean that person is more aware.

When I travel people who would never talk to me at home suddenly appear friendly. They are being comforted by something/someone from a familiar environment.

I am not questioning your motives, just offering another view to add to the theory.
