All the ones I talked to figured they had a maximum life expectancy of 35 before they were forced to find something else to do. Most wanted to be out before 30. A few were intending to bail out as soon as they finished whatever educational certificate/degree they were working on. I onlt ever ran into one who just thought it was great and a lot of fun and wanted to do it forever.
Did any of those girls have a Plan B ?
Most were college students studying nursing or business of all things. A couple wanted to set up their own "club" using their savings. All of them were extremely thrifty and were busy doing things like setting up college accounts for their kids (if any) and investing like mad. The only thing they spent money on were their costumes -- which became a tax writeoff.
Of course, this was over a decade ago. I'm sure the ones nowadays aren't quite as intelligent with their money. Making $1000+ a night can be quite addictive if you're not careful with the money. Then it goes away, poof!
