: Before there was economics, there was political economy, an interdisciplinary adventure boldly and critically seeking to understand capitalism. Over time, the social sciences evolved into specific disciplines - economics, sociology, political science - that less often questioned capitalist perspectives and the state. Contrasting three traditions - neoclassicism, Keynesianism, and neo-Marxism - Capitalism: Should You Buy It? traces the historical development of each and evaluates whether they view capitalism as the root cause of or the solution to the pressing problems now facing humanity. This accessible and hopeful book is a call to everyone - citizen, student, public intellectual - to revive the critical edge towards capitalism.
