Title: Beyond the Demonization of the Rich: Measurement and State of Wealth in four Latin American countries

Abstract: Considered one of the most unequal regions, for years Latin America attracted attention for its vulnerable populations. This concern was accentuated with market reforms, globalization and more recently with the Covid-19 crisis, that reversed the progress achieved in the first decade of the 21st century. As a consequence, the social sciences lost their relational perspective, interested in all social groups and, above all, in the relationship established between them.

The works of Thomas Piketty and OXFAM managed to arouse interest in "the rich" as fundamental links in the understanding of inequalities. In their publications, they argue that wealth is concentrated in a tiny minority of citizens who are located in the top 1% or 0.1% of the distribution. These diagnoses led to a moral judgment that reached the virtual demonization of the rich and reform proposals to raise taxes on their fortunes.

Although these approaches managed to reincorporate a certain relational gaze and illuminate the magnitude of contemporary inequalities. This project intends to go one step further. In order to interpret the specificities and mechanisms of capital accumulation in Latin America, it is necessary to open the black box of the notion of "rich" and, anchoring the reflection in the study of four major nations of the continent, explore their theoretical, methodological, and programmatic inadequacies. First, the notion of the rich, like that of the poor, ignores the historical and regional particularities of capital. Second, it is based on conceptual definitions and empirical evidence that do not have the same validity in all countries. Finally, the reform proposals in the region face limits that reinforce the objections formulated in developed nations, raising doubts about their relevance and effectiveness.

Combining economic, productive, and business history, information from national accounts, Forbes, wealth consultants and tax records, the case of Mexico, Brazil, Chile, and Argentina will be analyzed to advance in the identification of strengths and weaknesses in the conventionally used notion of wealthy, as well as in the proposal of measurements and characterizations more adjusted to the particularities of wealth in the region.
