The concept of wealth is complex to grasp, as it varies according to social, economic, and cultural contexts. Nevertheless, it generates constant interest in public debates. At what amount can one be considered wealthy? A recent study, based on data from the Bank of France and the criteria of the Observatory of Inequalities, provides a precise insight. It sets this threshold at 555,000 euros in net assets, far removed from the images of extreme luxury often associated with wealth. In fact, this figure, which concerns about 20% of French households, raises essential questions about wealth distribution and social inequalities. How does this definition influence our perception of wealth? And what are its implications for public policies and social justice?
