Most of us get exactly what you meant.
I work with the demographic of families described here. And have often called for children to be removed far earlier than they are.
But that doesn't mean that I think the problem is then solved and the children will go on to have great lives. Because in most cases they don't, and then I see those children getting older and having their own children and the cycle begins again.
Because we're not talking about 'psychopaths' who just sprang from the ground and had every kind of resource and benefits thrown at them and they couldn't be arsed to engage.
I can say 100% that sometimes they have been offered everything available and my compassion and patience runs out. But that doesn't mean I don't know that often, the people involved have been failed by social care/education/healthcare etc for years previously and often, their parents were and so we're dealing with generational issues caused by the social problems we have in the UK.
There are very, very few incidences like the one described here where it's a family who are middle class, earning, in adequate or good housing, well educated etc.
Same as there are few individuals in prison from those families.
And before anyone jumps on to say what a shit childhood they had but they still wouldn't do x, y or z. We know that having a shit childhood or life doesn't mean it is inevitable that means a shit adulthood or being a child abuser or shit parent.
But it happens. Often. The correlation is undeniable.
