In my grandmothers generation women couldn't work (although I know an 83 yr old single mom who did, it wasn't common). I've heard or read stuff like "women stay home during pregnancy, maternity leave, their monthly visit from aunt flo". Ok I guess that last one was irony. Well, since, as every body well knows, your true value matches the exact size of your bank account that did call for the women's rights movement.
Also there's this website called tv tropes that is a wikipedia by and for screenwriters and enthusiasts that describes "tropes" which is not stereotypes, but fairly close. It's believed that there's only so many stories in the world so all our literature, movies, songs, and thoughts rehash the same ol same old. Here's tv tropes + guy stud, girl slut. It has links to similar trains of ideas.
