Something similar happens in the UK. Local councils get cash from central government for every child taken from a parent and placed for adoption. They have a quota to meet.

A friend of mine got taken into hospital temporarily, and her kid went into care because she had no nearby family. Good mother, no abuse. She just got sick. I was away at the time, or I'd have taken him.

They started trying to remove him for adoption immediately while she was in intensive care. Zero history of abuse or neglect on her part. When she got out they made her go through a whole bunch of bullshit before she could get him back. They only backed off when it became not only was she way brighter than they originally thought (they even made her do an IQ test and were stunned to know it was about 120) but she had sorted out legal intervention as soon as she was out of the hospital.

They've taken to targeting chav single mothers too uneducated to fight back. It's pretty awful and most people have no idea what's going on.
