Researchers may discuss the poverty-shame nexus, however, given this study, I would include lack of formal education as being crucial to the mix—a poverty-shame-limited education nexus or cycle of lack—with poverty or lack of resources resulting in lack of education, which ultimately feeds into lack of honor or dignity, a sense of shame.
This insight helps explain why so many poverty mitigation projects fail--their educational component isn't connected enough to the rest of life.
