Maybe a solution can be making education easier. I don't think that the majority of Students in Nigeria need all this theoretical material about economics. A good solution would be teaching them how accounting works and how to work with bookkeeping software, which is all they need to start working. There is multiple bookkeeping software. You can find the most popular ones on playlouder.com. In Nigeria, using Quickbooks will be the best because it is universal accounting software that works for solopreneurs and big businesses.
