Another theory of the cause of the Great Gatsby Curve puts stress on consequences of redistributive policies emerging from the choices of voters. These models put a strong emphasis the role of the political process in determining public educational investments. The redistribution preferences of voters are potentially formed by their beliefs, and when these beliefs are influenced by inequality, another channel for generating a Great Gatsby Curve is being formed (higher inequality generates demand for higher redistribution - because the median voter becomes relatively poorer).
