Morethanpotatoprints - Not really. She is currently getting £32k per year. If you factor in free school meals for 7 children, say at £2 per day over 38 weeks, that is another £2,660, so £34,660 (only free to those on certain benefits). So a total equivalent benefits income of £34,660. You would need to earn just shy of £50k to take home that. Perhaps her benefits income should be taxed in the same way that someone earning £32k per year is currently, in which case she would take home £24,500.
I can imagine that all those families out there earning £32k per year but taking home £24,500 must feel pretty annoyed that this woman is getting £7,500 more than them without having to go out to work and that doesn't even include free school meals and other benefit freebies that people in work aren't entitled to.
