thanks for the thoughtful note. I hear a lot of these stories talking to people about aid programs of all stripes and sorts across Africa and Asia, and I do think there poorly designed programs out there that can end up doing a lot of harm. that said, researchers evaluating GD haven't found this, and systematic reviews of evidence on the impacts of cash transfers haven't found it- some links to get started
