We're going to school for higher education in higher numbers, but the numbers still show we're not breaking though the glass ceiling. For every Nancy Pelosi and Hillary Clinton there are millions of women stuck in cement on the floor that are not getting up.

In my research, I found that since 1979, women have lost the equivalent to one night's sleep due to the pressures of balancing work and family. And as more women have gone into the work force because they have to, and when you discriminate against a woman's pay you discriminate against her children or her husband or her significant other in terms of what the family income is.

I think in a society where you can't even pass the Equal Rights Amendment, it's very difficult to women make a progress. Incidentally, we are exactly 160 years after the very first women's public rights convention in Seneca Falls, New York, when a handful of women started it all and began the movement to make women equal.

While men's rights are guaranteed by specific language in the Constitution, women's equal rights aren't mentioned.

We cannot ensure that women will be free of discrimination in the workplace and everywhere as long as women are not universally defended under our Constitution. As it stands now, the equal rights of women are subject to interpretation of law. That is a risk our mothers, sisters and daughters cannot afford.

As more women have gone into the workforce, they find it harder to be a good mother and a good worker. When I go into the office, I always feel guilty. I'm thinking about the children. When I'm at home, I'm thinking about my work. So you're always under tremendous pressure. Women feel very stressed. They feel like they're working harder and harder and harder. And society is not really helping them.

I think that changing stereotypes and attitudes, it takes time. As we progress and we have more women astronauts and more women in construction sites and everything else, then we're making progress. Discrimination is deeply embedded in our community, but we do have the tools to combat it.
