There's VAST amounts of waste in the system. My mother-in-law who was a single parent and never worked much, got every benefit going. She had her rent paid for her, mobility allowance, PiP, pension credit and god knows what else. I was not close to it so I don't have the full list. But she never went anywhere and just accumulated more and more money. Eventually she went into a care home and thankfully the state got all but £23k of it back. But then of course she got all her care home fees covered as well. In addition, with her healh issues that went on for years, she had a house so full of unused drugs, she could have opened a pharmacy. She must have cost the state hundreds of thousands, having contributed almost nothing in tax and NI.
I wonder how many people like that we are all paying too much money to? Quite a lot, I would imagine.
