At least in my state, Therapists, social workers, caseworkers, GAL's, and most public defenders work for non-profit organizations. This means they will get paid the same amount no matter how large their caseload and no matter which way the case goes. This gives them absolute freedom to do what is best for the client and the child, not what is best for their own wallets. I have seen, however, lawyers and at least one therapist for-hire who have dragged out the case - likely for their own benefit. There are some things that simply should be non-profit (like health care).
