Abstract: The developing countries are highly motivated to undergo soicial transformation in order to get rid of the heavy loss caused by underdevelopment and being left behind.They paid a high price for this transformation.This includes the loss in value caused by conflicts between conventional native aspects and modern foreign aspects,negative effect of the influence of models provided by developed countries,and the high cost resulted from their disadvantageous position in international economic system.The author maintains that there exists a dialectic relation between social development and its cost.In fact,the history of social development is but a history of cost,and a history of paying and sublation.
