FGS OP- these threads are becoming so bloody tedious… but as you ask…
I think so many here are of the impression that obtaining PIP in the first place is a walk in the park, it really isn’t. It’s often months of sheer hell, uncertainty & yes, financial detriment, whilst navigating some real challenges.
Many carers to young adults will be on a limited income due to having had to give up their career. This means often that household costs are not just strained, they’re broken.
Many in receipt of PIP will be NEET , which not only means they lack the ability to generate their own income yet or at all, they are home full time & therefore consuming mch more in terms of food, entertainment, education & utilities.
Then there’s transport-petrol is expensive, many cannot take public transport, but may not receive motability… often means taxis or adapted cars…
Those with restricted diets, digestive problems all need safe foods which often is expensive.
Then there’s the need for tech, phone bills, Wi-Fi, all the things we all take for granted, but are necessary for education, safe access to the community, vocational & volunteer activities etc…
That’s before they have funds for any luxuries or social opportunities, your notion that disabilities generally come without cost is painfully deluded,
