The current economic crisis that plagued the west since 2008 and followed by the Occupy Wall Street movement in 2011, were the results of the processes started since the last years of the Cold War and has turned the western capitalist system into an unstrained ideology. The neoliberal economic model, globalization of economy, limitation of the power of the national governments, the emergence of new technologies, abundance of a variety of non-productive jobs such as capitalism relying on finance, resulted in the global power to be belonged to a few global capitalists, and thus class division becomes severe in the west especially in American society. The democratic institutions in the west and the media which often belongs to the capitalist ideology, not only failed to prevent this problem but they intensified it more. In this study, by situation analysis method and by examining the effective institutions and the current political and economic environment and the role of the capitalist system competitors, it has been tried to analyze the process of decision making in the US government as the main agent in pre and post Cold War eras. Finally it is concluded that actually the main reason of the unstrained capitalist system, more than anything, is the loss of the competing ideology in political arena.
