EXCUSE ME!!!!!!!!
I was a foster parent for 10 years. I adopted 6 of the children I fostered (all prenatally exposed to methamphetamine), and no, I wasn't in it for the money. I was a foster parent because I knew I was making a difference in children's lives, giving them a safe place to live when their parents were so strung out on drugs they couldn't take care of themselves, let alone their babies. I have seen you wouldn't even in your wildest dreams be able to believe, much less understand.
As for having no ties, the ones we adopted were children we fell so in love with that by the time they were free, they already felt like our own kids. We couldn't have bonded with them more if they'd been our biological babies.
MOST foster parents take in children for the same reason, and the ones who "do it for the money" are the exception, not the norm. The foster mothers I know are selfless, wonderful women who value the health and welfare of their foster children as much as their own. In it for the money? What money? Most of us spend much more on our foster children then we get reimbursed by the state for. Multiple visits to doctors, therapy and testing appointments, special equipment, easy-to-digest (and expensive) formulas- the list goes on and on.
When you end up staying up night after night with screaming infants going through drug withdrawal, you couldn't pay me enough to make it worthwhile if my objective was getting rich. It is a thankless job, made even more difficult by social workers who have to follow arcane rules and sometimes put bureacracy ahead of what's best for the children. You have birthparents who think our time is at their disposal, and I had many a ruined holiday due to demands from these selfish people. I got into a lot of trouble with social services for going to bat for several of my f. children who were too young to speak up for themselves when their caseworkers wanted to send them back to mothers who were manipulating the system and, IMO, not ready to parent.
Four of my foster babies were profoundly premature, two of my adopted children needed physical and speech therapy, and two grew up to have ADHD and learning disabilities. My oldest adopted daughter was so traumatized by physical abuse she received at the hands of her mother that we had bonding issues resulting in major acting out when she was 15, but we NEVER gave up on her. We never wrote her off with, "hey, you're adopted, we don't care, good luck with your life". I love my children, no matter where they came from.
And for your information, it might take 9 months to give birth to a child, but in California it takes no less than 2½ years to legally free one through the court system. When you have a child whom you've watched grow from an infant and you are attached to that child and you worry about a relative popping up out of nowhere to lay claim to him or her, it seems like forever.
I suggest that you refrain from making assumptions on a subject you obviously know NOTHING about.
