It sounds like you just don't understand why she did the things she did. You may not believe it, but many people don't feel stripping is degrading at all. You don't understand why she would, you don't understand what it's like to have to. To be blunt... it's pretty clear you don't understand her. At all.

Couples counseling is the only way I could see your relationship working out. You two seem to come from very different backgrounds. As someone who has known people with her background, and someone who has witnessed firsthand why a woman would choose (choice is important in whether it's "degrading" or not) to strip, and has struggled themselves in a similar way... I can't see this working out unless you learn to understand her past and to get over your judgment. From what I've read the problem isn't her past. The problem is your perception of her past.
