Minimum wage earner cannot afford to have discretionary income no matter how they try to minimize cost in Nigeria. The minimum amount for an investor to invest weekly is $10 which is around NGN 15,000 and the monthly minimum wage amount is NGN 70,000.
NGN 15,000 time 4 weeks is NGN 60,000.
NGN 70,000 - NGN 60,000.
What will be left to cover monthly expenses would be NGN 10,000. Which we know it is impossible to cover up their needs.
When someone says minimum wage, it doesn't necessarily mean that the worker earns the least amount. It is assumed that the tasks with little or no skills will earn the minimum, while graduates and those with high-level skills should earn above the minimum amount. Minimum wage is just the benchmark or the least a worker should earn.
Some people have other sources of income or who also get assistance from friends and family. It is also noteworthy that there are some states in Nigeria where you can have discretionary income if you earn NGN 70,000. In such areas accommodation and food prices are cheap.
