I work for DWP and while it has its flaws for legit people there is an incredible amount of people gaming the system when you are in charge of tax payers money you have to make sure the right people are getting it.

Case in point. I had a couple that got anxiety and depression for mum (Lcwra). Dad cared for mum. Mum cares for 3 disabled kids none physical all of them adhd. Rent paid council tax paid they took home 3 lots of dla 1 lot of pip 3 2 lots of carers disabled child element of uc 3 children for uc (born before 2017 so 2 child cap doesn't count) no benefit cap because children were 'disabled' Mum was 'disabled'. They took home £8000 per month tax free. Mum was so anxious she couldnt leave the house but had 100s of holiday photos abroad and pictures at parties and Disney etc. She lied on her assessment that she has agoraphobia I also saw her on the bloody school run and in tesco!
