The difference is that those places take the time to truly screen the women who work for them.  The mentality cannot be that of an abused woman who needs alcohol and drugs to cope. 

You have to have an interest in sex and why you enjoy it which is completely different from disconnecting to be able to have sex with a stranger. 

Those women aren't disconnecting in Nevada they are connecting with every single client.  Most have repeat clients.  The business is a family atmosphere and is unique in its qualities and structure.  You have to have real money to get into that place.  

Most businesses don't operate that way.  They are unethical and only care about profits and not the people involved.  Amber didn't care about the people in the trade she didn't even care about herself she knew she was damaged and wasn't trying to fix it.  So how was she going to make it better for anyone else?
