If content creators charged even half of what their skills are actually valued at, virtually no one in the poser community would be able to afford to buy their content. 

The average starting salary (in the US) for 3D artists is around 45K. 30K is low end, 60K is high end. For freelance work, $25 to $50 per hour is usually considered pretty fair, with $25 often jokingly referred to as practically working for free.

There's actually a lot more work that goes into creating content for poser than there is creating content for a game or film studio, which means theoretically speaking, poser content artists should be making even more than what a 3D modeller (or texture artist, or enviornment artist), at a game studio would be making, because the game studio modeler doesn't have to deal with all the extra bs that goes into creating content for Poser. They're doing the work of 3 to 4 artists in a studio, and getting paid practically pennies, if that, of what those 3 or 4 studio artists are getting paid, each. 

My philosophy is that content creators who really are good at what they do should reach a point where they start looking beyond the scope of the poser community to market their work, if their intention is to actually make 3D content their means of living. Most people can't expect to make a full time living off of creating poser content, even when their work is top notch professional. There is a large market for freelance 3D artists, and it grows every day. Poser can serve as a good starting point for freelance artists, but to expect it to be the sole bread winner is pretty delusional. There is a point you reach where your models are worth far more than you can sell them for, but you'll never get their true value selling to a hobbiest community.
