By emphasizing wealth creation, communities can not only cultivate streams of income, but also build wealth. Through collectively owned and democratically governed assets, communities can build wealth. Economic development policy and practice should emphasize wealth creation. Employee ownership, through worker cooperatives is one way to build wealth. But worker cooperatives are rare in the United States; this is because there is not a supportive cooperative ecosystem. The province of Québec, Canada has developed a robust cooperative ecosystem, leading the province to have the most cooperatives in Canada and a greater density of worker co-ops than the US. This thesis explores the Québec cooperative ecosystem through analysis of interviews with 22 leaders of over 19 organizations, including two worker cooperatives. This thesis seeks to understand (1) how the organizations and institutions in the ecosystem work together, (2) how they support cooperatives, and (3) how the lessons from Québec can inform the development of a cooperative ecosystem in New York City. This study reveals (1) the importance of historical, political, and cultural context in shaping the potential and possibilities for cooperative development; (2) that government support through policy, funding, and collaborative leadership is critical for the ecosystem’s development; (3) apex organizations are necessary to provide leadership and technical assistance among cooperatives; (4) interaction among cooperatives of all kinds leads to a stronger network; and (5) the size of the sector makes it easier to secure public support.
