Agricultural activities and little form of trading activities had been a mans of livelihood of people in different parts of Nigeria before the advent of the white men.
The coming of the white men into Nigeria brought change to this. Better ways of farming were introduced, economic activities came to being and grew, commercial activities expanded, the Christian religion was introduced in different parts of the country and political activities were introduced and grew too. All these activities called for the need to employ personnel into one position or the other. During this period, the word unemployment was not given birth to. Even after independence, in the 1960s and 1970s, undergraduates do not need to apply for employment. Employers usually woo them by depositing offers of jobs in their hall of residence for those interested to choose from as soon as they finish writing their degree examinations. During the period of oil boom, economic activities were generated in abundance and these made plenty of jobs available.
