Abstract: Amidst various reforms agenda, policies, development plans and programmes, Vision 2010, Seven-Point Agenda and a host of others, Nigerian leaders have articulated the Vision 20:2020, which targets to catapult Nigeria into the league of the first global 20 economies by the year 2020. This study used the critical research method to analyze and compare recent development indicators for Nigeria with those of advanced countries, the first 20 of which Nigeria aspires to join in 10 years’ time. In contrast to the situation in high-income OECD nations, the vast majority of Nigerians are ill-fed, ill-clothed, ill-housed and ill-educated. They live in the rural areas characterized by massive underdevelopment. Poverty is the basic malady of Nigeria which is involved in misery-go-round, as part of the slum of the world economy. Nigeria’s Vision 20:2020 is, therefore, too ambitious. And, against the backdrop of the antecedents of policy reversals, summersaults and failures in Nigeria, the Vision is utopian. Recommendations include commitment of the leadership to sufficient discipline and political will to enforce development policies and programmes.
