When Helping Hurts (Expanded Edition) by Corbett & Fikkert
I recommend everyone start here. This book has ignited a movement and is helping to steer us back from the damaging affects of hurting the very ones we want to help. Start here.
Poverty is much more than simply a lack of material resources, and it takes much more than donations and handouts to solve it. When Helping Hurts shows how some alleviation efforts, failing to consider the complexities of poverty, have actually (and unintentionally) done more harm than good.
