These are adults that require parenting.
It's particularly rife in people with addictions. And there is the issue of service providers explaining that addictions are a form of disease rendering the person unable to function in day-to-day living.
Even the supporting services keep them sick as they would have no service users.
Yes,yes, use funds put aside for the vulnerable and spend it on the privileged via stealth. Middle-class keeping the abused, disabled or working-class incompetent, blame culture, gives you virtue cookies and it pays for your holidays , builds you up a nice pension and pays your mortgage, what's not to like?
I have the immature parents. One has addiction issues, being male they had the attitude women should look after him and children, so there was nothing left for the children. Mum was so worn out caring for him, working and housework there was no parenting done.
He got to be a baby, she got to look a hard working wife whilst being be a baby too.
When Mum married the second time, she became a total baby minus housework, to look like a good wife. She stopped doing eventually she once did, laughs and claims it's her turn to be looked after and loves being helpless and wearing out her husband as her first husband did to her.
I don't know how these people think it's ok to use someone else like this. I suspect not every helplessness person that expects others to care for them, you need insight to be able to change, is as honest or self aware as my Mum who admits she is happy to be a selfish user.
Be you a public service vulture or a family/friend vulture, you take advantage of others and use them to advantage yourself.
