Mexico illustrates that equal access to education and the existence of public programs to support women's economic participation may not be enough to ensure that all women achieve equal life outcomes. These efforts fall short if deeper assumptions about inequality and exclusion are not considered in policymaking. If Mexico is to achieve shared prosperity, policies and programs must take an intersectional and holistic approach that centers the lived experiences of marginalized women in economic autonomy. This policy brief argues that the path to shared prosperity in Mexico starts by shifting the way policymakers think. The author's research shows that the mindsets of local policymakers in Mexico influenced policies related to women's economic autonomy and their outcomes for marginalized women, either by reinforcing exclusion or enabling transformative change. The author also demonstrates that policymakers' mindsets can change. The case of Co-meta, a second-chance education program, shows how proximity to marginalized women's lived experiences can shift policymakers' mindsets, helping them design and implement more inclusive, intersectional, and gender-transformative policies for women's economic autonomy.
