Restoring the American Dream: Insights from Big Data


The promise of the American Dream, once almost a certainty for the vast majority of children in the United States, has significantly diminished. Raj Chetty, a renowned professor at Harvard University and director of Opportunity Insights, delves into this issue with his talk, “The Science of Economic Opportunity: New Insights from Big Data.” Utilizing extensive datasets from anonymized tax records to Facebook’s social networks, Chetty offers a new perspective on economic mobility in America, highlighting a concerning decline from a 90% chance for children to outearn their parents down to just 50% over the last fifty years.

Central to Chetty’s research is the influence of ‘social capital’—the networks and relationships within a community that can either propel or hinder an individual’s economic progress. His analysis extends beyond the conventional focus on educational quality or neighborhood segregation to include the critical role of social interactions and their profound effect on economic mobility.

Through his analysis, Chetty sheds light on the stark disparities present not only across neighborhoods but also between racial groups, painting a picture of an opportunity landscape that is markedly uneven. The disparities, as the research suggests, are deeply rooted and become apparent early in life, underscoring the urgency of interventions aimed at young children in underprivileged areas.

In discussing higher education, Chetty points to a pronounced gap: students from wealthier backgrounds are significantly more likely to attend elite universities. This disparity not only perpetuates socioeconomic divides but also constricts the diversity of thought and innovation by excluding talented individuals from less affluent backgrounds. However, Chetty’s work suggests that promoting social integration within educational institutions can uplift students from lower-income families without disadvantaging their wealthier counterparts, advocating for policies that would open the doors of prestigious universities to a broader demographic.

The implications of Chetty’s findings extend beyond the academic realm, offering a guide on how to rejuvenate the American Dream. By pinpointing the characteristics of ‘opportunity deserts’ versus ‘opportunity-rich’ areas, his research provides actionable insights for policymakers and communities aiming to enhance equity and mobility. Chetty’s exploration into the “science of economic opportunity” serves as a call to action, reminding us that the aspiration for universal upward mobility remains attainable with dedicated effort and strategic interventions.
