I agree with you that this is a sad situation. However, I think you cannot compare two totally different countries and their wages as the living costs nowhere near similar in this two and therefore cannot be compared. A lot of countries have been struggling with a low minimum wage. If we go further from Africa (as I do not know about it that much myself) and would say focus on some European countries that used to be part of Soviet Union like the Baltic countries and since joining the eurozone they have had many struggles. Cost of living has gone up, but wages not accordingly. And it takes time for things to even out and to be fair and comparing themselves with other Western European countries won't do them any good.

Back to Nigeria though - what do you mean by "shut down the economy"?
