Google trends has Amy Schumer being more popular overall online than Chris Rock.
Out of the history of Hollywood, you don't believe there's a slant against women making money? It's quite obvious that it has nothing to do with talent or sales.
a few more thoughts on this
the disparity absolutely exists that's without saying
i'd argue it's even worse in the stand-up world
but schumer found a niche she could exploit and she did it masterfully
basically a less hardcore lisa lampanelli (who isn't palatable enough for the mainstream)
above the line contract negotiation can get hardcore, too
netflix isn't lowballing schumer because they hate women
they're just trying to get the best deal they can get away with
Rock and Chapelle may be seen as less relevant in some data sets than Schumer, but they are a known quantity. Netflix could trust the veterans to bring it, so all parties knew what they were worth.
Schumer's draw is a much more volatile demo, with a much higher chance at bailing on her if she slips up socially, which is much easier for her to do since she basically has to be edgy on social media or people will think she's lost her edge, and will bail anyway. There's more risk there.
this actually seems like a pretty good thread so far
i don't claim to have all the answers
but i do work in film accounting so i've been privy to a bit more
