I've had repeated experience of SS as a child in the US and, due to malicious reporting, more than a few experiences of SS as a parent in the UK, though I do not have the experience of going family court so not sure if my opinion is worth anything.
No system is going to be perfect. Natural ones are full of faults and human ones possibly even more so. I think there are things that will hopefully someday be stopped and improvements that should be made on both sides to protect vulnerable people, including kids. It will take a lot more resources and will than we have now. Part of the is going to have to involve the fears within communities both created by poorly handled cases and by people scaremongering (which yes, as a home educator, I have seen people who've never had any experience whatsoever with SS make some shitty claims, even make things up, so they can perpetuate 'the system is evil, hide your children' ideology).
I do think sometimes people - including some social workers - look away from horrible situations, particularly from charismatic and/or wealthy-appearing parents, for a long list of reasons, and at the same time, for many reasons, some people - professionals and otherwise - jump the gun and see horrors that aren't there. Most situations I think don't involve either of these though.
While I'm really not one to assume someone has someone else's best or any interest at heart - not because of their job or because they're that someone's parent - it does often feels social workers are damned if they do and damned if they don't and too often, even when mothers murder their kids, too many people make excuses (often involving how social services should have done more). Generally, I think most are just trying to figure things out and the system is most patchworked together to try to get things sorted. Having seen some of the docket involving my parents in court with each other which had SS involved, the amount of parenting classes and assessments they had to go through, I think the courts were trying their hardest to do something but kinda not entirely sure what to do. Or, if cynical, wanted to appear to be doing something while making money - those courses weren't cheap. Possibly a bit of both, that's one of the issues when trying to make a system like these, it's probably impossible to make an entirely perfect one.
