In this article, André Lara Resende explains how the logic of conventional macroeconomics creates a system of governance in the sense of restricting the financial power of the State for the benefit of financial capitalism, making investments in the well-being of the population increasingly smaller. The author argues that this ideological "straitjacket" of macroeconomics is, in fact, a threat to financial capitalism itself and that, therefore, it is necessary to break it.
