In this culture women earn less, have less rights, and are in many ways second class citizens. Women's contributions to work, in the arts or literature and science are all undervalued. At least that is the official version of social power. Women and children first' as the saying goes. Women don't earn less income than men either.
Some women earn much more than many men.
Most women earn about the same wages as men and if men earn more it can usually be explained by their greater qualifications, long hours or the difficulties and dangers of the job. Men do the hardest and most dangerous work in society. When women get married they often rely on their husband's wages, and the man must then try to stoically provide for the whole family. In courts female murderers can sometimes use the argument of 'battered wife syndrome' to walk free. Yet in some of these cases the women were themselves actively violent.
