Unconditional income improves parental quality.

"We find that parental interactions and experiences with the children in the affected households tend to improve dramatically. Both child and parent report improved behavioral effects and parent-child interactions relative to unaffected households. We observe that parent behavior, similar to criminal behavior. Previous research has found a direct relationship between poverty and parenting ability (Jane D. McLeod and Michael J. Shanahan 1993; Robert J. Sampson and John H. Laub 1994; Nicole E. Ennis, Stevan E. Hobfoll, and Kerstin E. E. Schröder 2000), and we confirm this result in our research. There is at least some indication that one of the mechanisms responsible for translating higher household incomes into better child outcomes is through increased parental quality, while parenting time does not appear to have been an important causal factor."
