I think if you check sugar, beer, name it, consumption is nearly where kenya is - despite the fact that kenya is uniquely private consumption ran economy. If you check beer - they are producing and consuming around 12M hectoliters - that lots of consumed beer - Kenya is around 10M hectolitres -and Nigeria around 16M - with South Africa - twice or thrice that.
Private consumption data - Look at cement production & consumption - Ethiopia came from nearly bottom - to now 3 in SSA. Way ahead of kenya.
