This paper deals with neoliberal and welfare conception of social development as dominant but mutually contrasted ones in contemporary political debates, and as crucial ones for interpreting global crisis. Their basic differences concern relation between state and economics in modern capitalism, with essential implications for an issue of actual global crisis. Policies based on one or another conception have determined a destiny of many generations throughout last two or more centuries and will significantly determine solving of this current crisis. There lies an importance of a comparative reviewing of these two conceptions. Parallel and comparative analysis will be offered. Value standpoint for evaluating quality and productivity of these conceptions will be taken into consideration. The main aim, however, is to stimulate a dialogue between them and to search for ways out from “trench warfare“, for the sake of contributing to solving the current crisis.
