I'm hearing you out, but I grew up in Nigeria and have been hearing lots of stories from friends who are back there working in businesses and forward-thinking foundations, and I'm excited at the prospect that huge percentages of young people will soon overwhelm the status quo with new thinking. I know business alone can't solve all the problems but I'm amazed at the sheer numbers of new startups I've been hearing about:
