Wealthy individuals ascending to national leadership roles around the world have captured widespread attention. This trend often raises questions about the extent to which these affluent politicians are willing or able to represent the interests of ordinary citizens. While much of the existing research on democratic representation has explored how politicians' background characteristics, such as education and prior occupation, shape their behavior, there is relatively little focus on the consequences of the wealth of politicians. Additionally, most studies have concentrated on political behavior in rich democracies, leaving a gap in understanding how these dynamics play out in other contexts. This paper examines the political behavior of wealthy politicians, focusing on South Africa as a case study. South Africa provides a unique setting due to its extreme inequality, with many previously disadvantaged individuals entering politics after apartheid, some of whom have accumulated significant personal wealth. Indeed, legislators across African democracies are disproportionally more educated and coming from professional and corporate backgrounds than citizens, compared to democracies in Europe and the Americas. Using newly collected data on the assets of Members of Parliament (MPs), parliamentary questions and speeches, this study investigates whether wealthier MPs engage in different parliamentary behavior, particularly on policy issues that could have self-interested consequences, such as taxation. Our findings contribute to the broader literature by offering new insights into how wealth influences political behavior and representation, particularly in the Global South.
