My understanding is that there are live-in role models/mentors and foster caregivers. Most are mentors, who are nothing more than glorified roommates, which is where the problem begins.
These are the people who are in it just for the money, generally not the foster caregivers. These people are the easiest to find because they really don't have much responsibility. They just supply a roof, food, and clothing; they have next to no say in the behavior of these children and teens, and don't want any. These so-called mentors are usually in the low-to-middle income brackets, and in most cases are single. Child protection laws allow records on all involved to be kept confidential, so it is almost impossible for even investigative reporters to obtain information. DYFS is essentially an agency cloaked in secrecy.
I have caught a mentor, living in an apartment below mine, having sex with a woman in front of a mentally disturbed foster male teen living with him. On several occassions the boy would walk in on him, while he was having sex, and stay for the duration. The mentor and his friend would neither yell at him or stop what they were doing. I notified DYFS and they replaced the mentor with another idiot. The mentors never disclose their relationship, and the mentally disturbed teens ( many of the foster children have maladaptive behavior, and are kept hidden in the apartments) are allowed to run at night.
I was a foster child who was fortunate enough to be adopted by my foster caregivers at a very young age. However, the majority of those sheltering todays foster children are not foster caregivers, although that seems to be the title DYFS prefers to use; they are really nothing more than services-for-hire. This is the way it is, and this is the way it will probably stay!
I am thankful I was a foster child in the 50's and not one today.
