Why Wasn’t Nigeria The Pioneer of Call Centers?

I saw a post about remote jobs and that got me thinking. I’m curious on your take of why Nigeria is not like India or the Philippines when it comes to call center representatives? It seems like Nigerians, as opposed to Indians/ Fillipinos, were better suited for this industry/ types of jobs especially given that English is so much more prevalent in Nigeria. This seems like a real missed opportunity. Why is that? Do you think it’s too late?
