We must not lose sight of those facts which make the question of woman's labor a complex one. An important and thoughtful woman recently made a study of the women in the Renault factories; she states that they would prefer to stay in the home rather than work in the factory. There is no doubt that they get economic independence only as members of a class which is economically oppressed; and, on the other hand, their jobs at the factory do not relieve them of housekeeping burdens. If they had been asked to choose between forty hours of work a week in the factory and forty hours of work a week in the home, they would doubtless have furnished quite different answers. And perhaps they would cheerfully accept both jobs, if as factory workers they were to be integrated in a world that would be theirs, in the development of which they would joyfully and proudly share.
[Beauvoir, The Second Sex (Parshley tr.) p. 680]
And this, I think, close to the point: it's not enough to treat women as men are treated now; both women and men need to be treated better than men are treated now. In many cases it is more clearly crucial in the case of women; and as an interim measure, the goal of equalization is quite reasonable. But equalization is a means, not an end, because we should not stop moral progress at mere equality. People can equally be treated badly; and this is just not good enough.
