What is causing success?

Barrett explains that there are three things that must happen in order for women to be liberated from their oppression without totally destroying capitalism. The labor and childcare responsibilities must be deconstructed systematically, women need to no longer be actually or assumed dependent on men's wages, and the ideology of gender must be changed. This is all according to Barrett, in the 80s. Today, the classical family structure where the woman stays at home and the man wins bread is much less common. It is easier for women to get better jobs (there are women among the richest people and CEOs of the world), and higher social positions (see: the current and last presidential races). We haven't completely switched to gender neutrality, nor what Barrett was hoping for, but we are much closer (and perhaps still on our way). What, then, has been the cause of this change? It could be that feminism is effective, that one or more of Barretts points are actually happening, or simply that we are becoming farther and farther from the causes of the current 'oppressive' structures.
