Disparity in offered income

Hilary Swank discussed to her interviewer how she was offered only $500K for a woman role compared to the 10 million offered to the male co-star who had less marque value than she did. I can sympathize with Swank and I think I would also have been outraged at being low-balled for a acting salary when I knew I was worth much more. However I think I know the reason: Hollywood's hypocrisy about women. Hollywood loves to champion itself as a bedrock supporter of women's rights but is the first to throw women under the bus. When actresses age, Hollywood has little use for them. True there have been actresses who achieved continuing work and fame after their prime years but they have been few and far between, and usually filled roles of classy older women characters. Hilary Swank got older, that's all there is to it.
