There are also security issues. Indian cities haven't been very safe for women especially for women working at night. Crimes against women are common. Also there lack of affordable places like creche's and day care centers for kids preventing women from working post maternity. Most working women quit jobs for this very reason alone.
Secondly, even if women work. The situation in India is worse enough to make them spend that money on their own selves and their families, than their parents.
But I agree, with you that women must be encouraged to work more.
Only 60 years ago it was common in the western world that women had to stay at home to take care of the family and household chores. I don't think it was only feminism that changed that, but also technology. For example washing machines probably saved a lot of time (even a bachelor can wash their own clothes these days). Not sure how widespread access to such technology is in India?
GDP per capita is about $3500, adjusting for PPP. 31% of the population has improved sanitation.
So, washing machines are not very widespread.
