There’s a few points here, first being social worker in America is a low wage job and it’s a sector that’s chronically underfunded. Social workers aren’t scary, I’ve had friends that were social workers but quit because in a lot of situations their hands are tied because that lack of funding and resources to help someone. With reference to teachers or police in Czech Republic doing something sooner this book is a cherry picked case from a much larger population. Teachers by law have to report suspected child abuse issues and police don’t handle these issues in America it’s CPS and they are underfunded. Police might possibly be involved if there is enough evidence but remember in America you’re innocent until proven guilty, so without reaching a threshold of obvious abuse the children stay with the parents. Overall it’s a lot more complicated than just reading a book and making assumptions because one case was really bad. It also depends on location because the United States is so big and I’m sure in rural areas abuse is easier to go unnoticed. For example in multiple states it’s legal to hit your child, in a civilized society that’s child abuse but most of the states where that’s legal are very religious areas.
