In the mid-1970s, the tiny Canadian town of Dauphin ( the “garden capital of Manitoba” ) acted as guinea pig for a grand experiment in social policy called “Mincome.” For a short period of time, all the residents of the town received a guaranteed minimum income. About 1,000 poor families got monthly checks to supplement their earnings. Evelyn Forget, a health economist at the University of Manitoba, has done some of the best research on the results. Some of her findings were obvious: Poverty disappeared. But others were more surprising: High-school completion rates went up; hospitalization rates went down.
