I was searching for Nigeria and finally I saw it but no data is inserted there. And currently in Nigeria the minimum wage is #30,000 which is equivalent to $38 and the inflation rate is much more higher than the minimum wage in the country so hunger is the talk of the day. A bag of rice is sold #40,000 ($50) and minimum wage is $38 so when the monthly salary his received by the workers they would used it to pay debt. Minimum wage in some country  is very small that the workers are not using it to do any better things in their lives but to pay debt and feeding.
