This study will work on debt as political relation. Relations of power in society, which gives frame to our perception, life and decisions, will be the essence of this study. Debt will be understood as fundamental relation and relationship in society. We will show and point out the omnipresence of debt in our life and relations. We will try to show, how is debt manufacturing us as a subject of governmentality. At first we will, through concepts of Marx, research and show the operations of credit system and we will understand debt as capital and as primitive accumulation. Credit makes accumulation of capital possible, by that it makes possible the development of capitalism as such and that is why, it is indispansable for the system. But, because governmental rationality can not be economy itself, we focused on the other side of the coin as well. We studied the debt as political relation and as governing relation. Today the debt manufactures (governmental) subject of neoliberal governmental rationality of the state and the (financal) markets. This means that study is revealing what, to who and how much are we in debt.
