I've written past comments on HN about how I was raised by a father who was a professional con man who committed credit card fraud, drove family into bankruptcy, then ghosted on my mother and I. The depths of that process was deeply chaotic and disruptive at a formative time in my life (high school and college).
I've ended up having a solid career, but I have no doubt I'd have been able to make a bigger impact if the family drama hadn't dragged on my time and focus for years (basically in supporting my mother through the experience). Society's answer (at least in America) is basically to say "you could cut out your family if they're destructive" but that goes against one of the strongest aspects of human nature (to have a family). Choosing between chaos and isolation is a terrible dichotomy and a big job of society should be to ensure individuals have other warmer options.
Also identifying earlier and stopping those chaos agents like my father is an area of study that is under-researched compared to the upside for society in solving that problem. There are folks like the Mind Research Network (https://www.mrn.org/) working on this but IMO should be getting 10x the funding they currently do.
