<i>but the government shouldn't tell you what changes you can't make to your body, or how you provide care for a member of your tribe.</i>

Talk to a social worker and see whether or not you still believe that a government should still be able to step in and tell you how to treat a member of your "tribe"

I remember reading one social worker's long diatribe about why they burned out and quit. Out of several truly horrible things (black and blue children are ten a penny), the one that really stuck in my mind was the description of finding genital warts on the anus of a 7-year-old because his mother repeatedly whored him out.

"Self regulating"? Bollocks.

I'm against the abuse of children and happy to use the government to accomplish that.

However, the prevalence of abuse and neglect in the foster care system - complete with cases on that order of horror - makes a very weak case for the idea that external regulation accomplishes any better.

So... a program where near to 100% of input kids are neglected or abused that ends up with a significantly lower proportion of those kids neglected or abused is a "very weak" argument that anything has become "any better"?

If you had a drug that could save 50% of terminally ill patients, would you say "we have a very weak case that this drug saves lives"?

In order for your statement to make sense, the failure rate of foster care would have to approach 100%. Again, talk to an actual social worker about how they see foster care and whether or not they choose to use it. It's an opinion that will most likely come with caveats, but foster care is also a service they use frequently.

"near to 100% of input kids are neglected or abused"

Untrue. Children end up in the foster care system for a variety of reasons, including simple loss of parents or a woman (or teenage girl) knowing she can't care for a child.

"significantly lower proportion of those kids neglected or abused"

The evidence is not as clear on this as you'd like it to be.

To correct your example, if we had a drug that caused strokes or death in a significant percentage of cases, simply saying, "Well, many of the patients we'd give it to would otherwise suffer strokes or death," would be a quick route to an FDA rejection.
