Final answer:
Conley suggests that the MTO experiment showed that social divisions are a greater barrier to overcoming poverty than income alone, as issues like racism and segregation continued to affect participants despite increased income.
Step-by-step explanation:
Conley concludes that the results of the Moving to Opportunity (MTO) experiment show that "income is not the main problem, social division is" primarily because the experiment demonstrated that social divisions, such as racism and segregation, play a significant role in poverty. This conclusion aligns with the interpretation that even as families moved to neighborhoods with more income, these systemic social issues persisted, limiting the overall effectiveness of mere income increases in resolving the deep-rooted problems of poverty and inequality. The findings dovetail with broader sociological discussions about factors like access to quality education, employment opportunities, and exposure to crime, which remain unevenly distributed across social divisions.
