I think margins are going down and there are plenty of stories of women being completely stuck in a world they don't want to be in, some of them actually struggling with mental issues. Sure, some probably like it but I can understand that companies prefer not to be associated with a world that seemingly contains a lot of misery. There are plenty of documentaries about the industry, they don't paint a rosy picture.
I understand the down voting and I also understand your response. But wouldn't it be nice if there were fair-trade porn sites? Where we know people are treated an paid well? It's insane that there is so much for free while there is so much work involved.
If they're doing legal business, why should they?
