Viable careers have opportunities for advancement. In prostitution and pornography aging leads to less interest. Such work might suit students who need to pay their ways through college but as a career? I don't think so but could be wrong.I'll finish my thoughts here by further examining how either pornography or prostitution should be presented to the young as career choices. Are such to be swept into a general mass like Manufacturing, Retail, Finance, Science, Accounting, sheet metal worker, MRI technician, in our desire to destigmatize the two Ps? Or should some few be called to the side and counseled that, because of their looks, freshness, boldness, etc., they might ponder P or P as viable careers? A tricky situation.
I did know a woman of about 30 who paid for her PhD (in some form of astrophysics) by advertising her services to men who like to be treated like babies. This work did not involve her in offering sex but did mean being comfortable spending some time with some pretty weird men. I don't know how she tolerated it but can say that as soon as she got her doctorate she got a "proper job" in her field. One thing she needed when she was offering her mothering services was someone nearby who would ensure her safety if she was dealing with a dangerous madman.
