Hernando de Soto saw in Lima's shantytowns not poverty but frozen wealth, homes held by custom that title could turn into collateral and growth. The idea reshaped development policy, then studies showed what a paper title can and cannot do. The episode lands on a reframe: security of tenure is not the same as paper title.
Critics question whether the $9.3 trillion figure was ever defensible and whether titling causes dispossession or merely coincides with it. Whether the weak credit channel is permanent or immature, and how to judge de Soto's legacy, remain contested.
