 Such social norms could be addressed through education or through media campaigns promoting the equitable division of housework. Legal measures such as requiring all marital income to be held equally could encourage power equality within marriage (Okin 1989, Chapter 8). However, state interference in on-going marriages arguably conflicts with spouses’ liberties (Rawls 1997, 787–794). This seems to raise a theoretical problem for liberal feminism. Recent liberal feminist approaches to marriage focus on how a just law of marriage can protect women’s interests as well as supporting a fairer distribution of care work, which often falls on women (Metz 2010, Brake 2012, Hartley and Watson 2012, Ferguson 2016, Bhandary 2018; see also reform proposals in 4.4 above).
