National development of a multicultural setting requires a decentralized appropriation of diverse contributions of various constituent subsets. Improvement of multicultural settings calls for social negotiation and economic merger, and compression of individual resources of the various units to enhance egalitarian level of advancement. However, the Nigerian government employed a centralized authoritarian administration that undermined the value of economic relations and national development since military rule in 1966. Centralization of the control of economic and entrepreneurial ventures culminated in economic deprivations among the states and regions of Nigeria. Consequently, increase in level of poverty became pronounced while resources of development existed untapped in the local areas. This paper employed historical critical analysis in contextualizing solutions to the above problems while suggesting the need to encourage individual creativity in entrepreneurship in order to enlarge multi economic relations for national development. It concluded by recommending Israelite egalitarian system of stewardship and accountability for a decentralization of economic control towards improvement of the rural constituent regions. There should also be fund from the Federal Government to establish industries in the rural areas. There is need for exploration of resources at the local areas by local trade societies saddled with stewardship of 20% of gross local products to the Federal treasury in order to expand employment opportunities.
