Part of the reason there is a glass ceiling is because of many reasons..some of which I'll list.
1) Men are pigs and sexist..blah, blah, blah..sometimes true.
2) Women usually never dress professionally..I've worked in 3 different fields where I had to wear a shirt and tie, and/or suit everyday, and the women who worked at higher, equal and lower positions mostly wore glorified t-shirts and all sorts of inappropriate clothing.
3) A large portion of women at said companies/workplaces were always whining and complaining about the most mundane things.And spend way more time making personal phone calls on worktime.
4) Women are always taking time off work to stay at home with their kids. Sad fact, but true. women miss waaaaaaaaayyyy more work than men.
5) Women have the disadvantage of becoming pregnant possibly. If you are in an important position becoming pregnant is a severe hardship to the work environment where you are needed. This is why in most cases middle-aged and older women are the ones to get promotions, even if a younger woman is more qualified.
6) Men are usually more willing and more capable of putting in extra hours at work.
7) Etc.....

Granted many of the traditional roles are changing nowadays..more women are making more money. Many Men are now staying home. There are more options out there. There are more Companies willing to work with family medical leave , etc. But mostly because they have to. As the typical nuclear family has changed to meet the goals and needs of Feminism women have found new options and more available choices. But as women got more freedom they also became a bigger liability. With the destruction of the typical nuclear family also came.......more single Mothers. Companies will hire single Mothers, but they are a pain in the rear from an employers POV. More missed days, more flexibility needed, more out of work problems that carry over into work. It's a fact. It's hard to promote someone with those possible circumstances as baggage.

Women with degrees are more likely to postpone motherhood, more likely to to view their job as important as their family life, etc. But those stigmas attached to female workers are real to an employer.

Feminism is an ideal. It's unrealistic. Because Women are women and men are men. Thank evolution and/or god.

And there is no difference between women having sex freely and women getting paid to hav esex freely. There is no difference in women wearing next to nothing in public and women getting paid to wear next to nothing. Except that some women get paid for it. respect their ingenuity, because perception is the only thing that make sit different..because the intent is still there.

Perception..woman wearing a small 2 piece bikini on the beach...Ok....
Woman wearing a bra and panties..only for private.

That's strictly perception, as only the see through kind allow you any more view of the same body parts.

From a religious standpoint most women do degrading things on a daily basis. Atleast some women are clever enough to get paid for it....
