When disaster strikes, who profits? That’s the question asked by journalist Antony Loewenstein in his new book, “Disaster Capitalism: Making a Killing out of Catastrophe.” Traveling across the globe, Loewenstein examines how companies such as G4S, Serco and Halliburton are cashing in on calamity, and describes how they are deploying for-profit private contractors to war zones and building for-profit private detention facilities to warehouse refugees, prisoners and asylum seekers. Recently, Loewenstein teamed up with filmmaker Thor Neureiter for a documentary by the same name that chronicles how international aid and investment has impacted communities in Haiti, Afghanistan, Papua New Guinea and beyond.
