I've understand that many women who are barren visit Rachel's tomb for inspiration, and perhaps for some sort of divine intervention.
My understanding of Rachel is that her fate was very much determined by her own doing. In Bereshit 30, Rachel was very frustrated because she was barren, to the point that she wanted to die if she couldn't concieve. She made a deal with her sister Leah. In exchange for Ruben's dudaim so that she could bear children, she permitted Jacob to sleep with Leah, who herself had become barren after already having had four sons. Although Rachel was able to bear Joseph to Jacob, Leah bore him two more sons and a daughter. So because of her jealousy and need to be instantly gratified through medicine, compromised her position as favorite wife, similar fashion to Esau selling his birthright to Jacob. It may explain why she is buried on a side of a road seperate from the other patriarchs and matriarchs.
She also valued her fathers idols, and was unintentionally cursed to die by Jacob for stealing his them. For when Laban came looking for them, she hid them under her dress and looked him father square in the face and said " I cannot rise before you, for the way of women is upon me.", so that she would not reveal them to him. This may be the reason that she dies giving birth to Benjamin because she has used the excuse of her menstual period to manipulate her father.
She placed more value on being a mother than a wife. She also uses her feminine nature to manipulate the men in her life. Perhaps this is why feminists like her so much.
