Sure they're not billionaires but if you're smart you can make enough for a very comfortable living. Porn stars these days aren't solely relying on performing on camera as their primary source of income. They're now branching out to doing club appearances, feature dancing, endorsements, cam shows and phone chats, sex toy lines, etc.
The days of the super star millionaire porn stars like Tera Patrick and Jenna Jameson are over. Is it impossible we'll have another one come through the industry? No, but I think they're very rare birds.
However, I think just like any other person, if a model is clever and is willing to work her ass off, she can make a pretty comfortable income middle to upper class. Especially if she invests and creates her own businesses.
