However, in most cases of the sample in the study, the dynamics ended in a mutually dependent relationship, where the womans income is needed, but at the same time women have to do the majority of the housework, their well-being is seriously affected. Another variable that changes the dynamics is time, according to the research (Schwartz and Pons, 2016), there can be the assumption, that could explain how the dynamics star changing through the past decades, at the beginning of the 1970s the traditional dynamics was that women did the house labor and that men work for income because literally, they were in a system that made men much more capable of bringing more income to the family. However, theres also noticed that the few women who out-earned their husbands were more prepared than the average men, but they still earn less than the average men, for discrimination issues. Eventually, the feminist movement changed the patriotic system, and women started earning more. The dynamics of couples started changing in the 1980s, correlations between higher income of women and higher rates of divorce, started decreasing, because the dynamics had already changed. People were getting more used to changing traditional dynamics to bring more income to the family. This effect is supported by the previous study of Roger (2004). Finally another variable that was analyzed, is the economic independence theory, (Rogers, 2004) establishes that if one side of the couple provides more than 60% of the total income of the couple, theres a dependence effect.
