You are now being juvenile, but to dissuade your ill informed thoughts. Manufacturing grew at 4.2% last year. The price of beer quoting the example you have given, is due to sin taxes ie A tax meant to reduce consumption of a product not currency but eabl still grew it's profits from increased output ie. They sold more beer last year than in 2017. so giving an example of beer in an sector that manufactures for the whole east and central africa and to make it worse an irrelevant example is puerile to say the least.
