Do men degrade women or do women degrade themselves?

We always hear that men are degrading women by using them as tools. Whether it be in magazines, commercials, tv, photos, music videos, the names the use in reference to women. But dont women have a say in all of this. No one makes a women get involved in any of this. All a rapper or celebrity has to do is put an ad in the paper or casting online for their music video or production and 1000 women will show up half naked. What happend to the backbone of women-society? Yes there are plenty of self respecting women out there I am very aware. Its just the way men are blamed for everything. And yes I do understand that this is a men driven society which makes it all the harder, but how does the that make a women want to pose half naked for a budweiser commercial. Obviously something deeper is wrong or money is power. Im intersted in hearing others opinions on this.
