Scholars of the political left-right divide often see equality as the core issue of contention, with the left seeking greater equality than the right. Though partially agreeing with this consensus, I propose a modified left-right conceptualization that offers three novel contributions. First, while accepting the idea of a single fundamental dimension underlying conflict in global politics, I argue the key issue is not necessarily equality but rather the diffusion or concentration of power within and across nations, communities and individuals. Second, given the inescapable complexity of politics, I argue in favour of distinguishing between those who seek to de-concentrate power and broaden inclusion (the left) from those advocating for a concentration of power (the right) in specific issue domains. Third, I illustrate the utility of this “one dimension, multiple domains” theoretical framework through a comparative analysis of eight contemporary political parties across the domains of economic, foreign and social policy.
