For more than 25 years, the casino lobby has told the American people that casinos are the engine to help Native American tribes prosper. Now The Economist, the world’s leading international magazine, spotlights how casinos have actually made tribal members poorer, pointing to a new study in the American Indian Law Journal showing that growing tribal gambling revenues can make poverty worse. The study looks at two dozen tribes in the Pacific Northwest between 2000 and 2010. During that time, casinos owned by those tribes doubled their total annual take in real terms, to $2.7 billion. Yet the tribes’ mean poverty rate rose from 25% to 29%. Some tribes did worse: among the Siletz poverty jumped from 21.1% to 37.8%. Below is both the story from The Economist and the study from the American Indian Law Journal.
