That may well be true for your one experience in Tanzania. I wasn't there with you. I have neither a reason, nor the desire to counter your personal experience.
Here's what I find baffling. You had a single, curated, extremely limited travel experience, in (I'm guessing) a handful of places, in one country, over a limited time period. You extrapolated from that experience to making a bold, sweeping claim about an odd 1.2 billion people living in 54 countries. And with an air of worldly confidence, to boot. What you said of Africa is not even generally true of the city of Dar es Salaam, let alone all of Tanzania. How could it possibly be true for a whole continent? I'm genuinely in awe of both the audacity it takes to make such a claim, and the thought process that leads to it. I do feel a bit bad for singling you out (but only a little bad) since it's sadly not unusual for people to choose to talk about places in this way when they don't expect to be challenged.
