People like Rihanna have the luxury of earning millions of dollars from something totally outside of anything in the industry. She doesn't face the risk Nikki does if Nikki screws up her career by making a bad move. Even still maybe Nikki just plain doesn't feel like going further yet or ever, and people in the industry setting lines for themselves is fine by me for almost whatever reason they choose to do so.
Nikki is also one of the most successful people in adult entertainment's history in longevity, notoriety, and yes I would bet monetary wise also. I think she knows what she's doing more than you or anybody else that comes here to complain about her do considering there are countless full on pornstars out there that haven't had a fraction of her success. More likely is if she would have went harder she would probably have been another washout years and years ago, and would be rarely remembered now.
