I generally agree, but for whatever reason (lack of life skills, bad social circumstances, inability to cope, disadvantaged backgrounds, mental health crisis, or whatever other reason) some aren't.
Whether it's lack of will or ability, it's happening. So what do we do? Nothing? It's not fair on the child, and even if people don't care about that it affects all of society. All of us. Financially and or just the general impact on communities.
'Feral' kids grow up to be adults struggling with social problems and then repeat their childhoods with their own kids. Then we have more social problems affecting our towns, cities, and villages, and everything just gets worse and worse.
Investment in early intervention and support services, improved CMS system, and better opportunities (jobs, education, training, housing, access to healthcare) will help break the cycle.
Also, and this is probably a bit controversial and I don't think I'll explain what I mean well, but I don't think the current housing system helps. DC mean automatic priority and eligibility for housing. When there's lack of opportunity and a disadvantaged backgroud, having DC can be seen as the best ambition or option.
I'm not suggesting families shouldn't be housed. Children need homes, and whatever anyone thinks about how responsible or not their parents are, the kids shouldn't suffer because of it. Also it's not simply 'irresponsibility'. Circumstances can change, unplanned life events happen.
However what's really needed is more social housing for everyone including single people and childfree couples and better work and training opportunities and good public services.
