The problem is the same as for any disbarred attorney or delicensed doctor, I guess; or a real estate salesman in 2008… The thing you’ve done for a while, and what used to be easy money, is gone. I suppose the advantage with sex trade of various types, is that it peters out (sorry) instead of disappearing overnight. This would give the person more time to adapt and contemplate the future if they are the contemplative type.
SO really, the question is - what do you do if the easy money runs out, and you don’t know anything else?
The answer, like eevryone else, is either - as mentioned above - work at IHOP or similar entry level job, or learn something new. I suppose the only difference is they are less likely to tell people about their resume.
I see that as a net disadvantage. Because if you lose your license, you know it’s over and you need to do something else. But if you gradually age, you kind of slide along. Each year is only slightly worse than the year before and the change is imperceptable. Which is even besides for the fact that ordinary fluctuations will hide the decline even more.
[I once spoke to a guy who was once an egg farmer in NJ. The egg farming business in NJ is gone for decades. In retrospect, he says you can see the big picture - once refrigerated trucks made it practical to produce the eggs closer to where the feed was grown, the business was doomed. But he said that at the time, this was not apparent, because there were other factors at play and ordinary fluctuations from year to year.]
