Have you ever tasted Ethiopian food? You haven't? Don't worry they haven't either.
Is this joke meant to be at other peoples' expense?  I don't think it makes someone look smart to say things like this.
In a way yes i do feel smarter than them. They live in a shit hole and they are probably poor because many of them don't have the ability to make money.
It can be very offensive to Ethiopians, and to all people of African descent, to suggest that they are all starving.  There were severe droughts in the past, but most of the continent is thriving today, and it is worth reading about or watching documentaries.
