In this industry, much like a lot of business' that rely upon beauty, there's only so much time you have to make the 'gravy' money.
When you get into the business and your new and fresh and everyone wants to work with you, you can make SO MUCh money over a short period of time.
But you have to realize that this isn't the type of income you're going to make for life, and unless you invest it correctly or save it (as oppossed to spend it as quick as you make it), you have one of three options:
1. Take on assignments that you might not normally do with people you might not normally work with(Which is a risk), so you can try and mantain that income level.
2. Learn to adapt your lifestyle to a change in the level of income your making.
3. Get out of the business and become bitter.

I've worked in the strip club business for years and have seen this same type of thing happen over and over. Girls who were making $3000-5000 a week, suddenly having to survive on $1000-1500 a week.
The smart ones learn to adapt.
The less fortunate ones get into debt, more expensive drugs, start hooking, etc.

As far as degrading yourself, well, that says it all. If you're careful, safe, smart, and don't do anything you don't want to do...then it's only degrading to you if you decide to let it be.
I don't mean that in a disrespectful way to Jessica, but she got to live the lifestyle that some people can only dream of. Sex, money, fast cars, the best clothes, drugs, center of attention, star of the show...
I know we haven't heard the whole story yet, but something tells me we're not going to hear anything that surprises us.
Sorry.
