We are hardworking people in Nigeria, but there is no job and we are too many. Go to tailor, barbing saloon, shoe making shops and others that you mentioned to see that you will people that are leaning all these works.
Not that some people don't want to acquire a skill or learn a trade but due to high level of moral decadence and inpatients amongst young people of this generation that why it seems as if people don't want to learn, many are carried away with hopes of making it fast without building capacity through learning and that's why you see them go broke not too long after hit some good amount of money, because they refused to learn the basic principles of how money works especially those who are into cyber crime(yahoo boys).
