@Arnold: Perhaps you'd like to keep an adult, a 14 year old who is growing at a rate of knots and 4 year old on £70 pw.
Thanks to the benefit cap, this is what one of my clients has left to live on after paying the (large) top-up to her "affordable" rent, 20% of her council tax and her water, gas and electricity charges.
She's an excellent manager of money, shops around, meal plans, batch cooks etc. She walks miles rather than pay £5 bus fare to get to the nearest town with a proper supermarket; she walks 6 miles to and from the job centre every fortnight. She only pays £5 a month for her mobile and £20 a month for internet. She manages to squirrel away a pound or two most weeks so she builds up a little stash for replacing essential items.
Despite all that, she still had to resort to food banks when her youngest started school and she had to buy her uniform, when her son's school became an academy and completely changed the uniform and when her washing machine needed repairing. The only new clothes she has had in the last few years have been gifts. She has to buy 2nd hand bed linen from charity shops. Her towels are so thin they wouldn't even pass muster as dog towels in my house.
This is absolutely normal for families on benefits in the SE, where rents are high. I could give you case study after case study of real families who are struggling like this.
"Fake news" is the shite spouted in the DM etc when they spew bile about scroungers etc.
