PIP is indeed to help people with disabilities to have independence. It isn't a case of giving the PIP only to people who are employed, and I cannot believe you really think that.
My point was that the physically disabled usually do need to buy help or equipment with the PIP, and if the recipient has MD, and has to buy help with the PIP, then they should receive it.
If someone has MD and is unemployed, and on other benefits, and does not use the PIP to buy help or equipment, should they also get PIP?
It is a question. At the moment everyone gets it whether they spend it on help or equipment or not. If someone suffering from MD does not need any more help than a non-disabled person, why should they receive PIP? Their condition may be corrected with drugs, as with those suffering diabetes, or thyroid diseases.
Not all diseases are debilitating. Some are corrected with medication. Mr. Streeting is referring specifically to very great increase in mental disease claimants, and is rightfully challenging the system.
I didn't vote for him. I wish him luck. It isn't easy to have to take benefit away from those who rely on it, but neither do I, as a tax payer, want to give my hard earned away to someone who shouldn't have it.
