Nonsense.
Billions of £ get stashed away and tax avoided, vastly in excess of the tiny bit which gets lost with "benefit fraud". In fact figures say that more is probably unclaimed rather than is fiddled.
What the establishment, oligarchy, financial world, the right, etc etc want you to believe that everything that is wrong with the world is the fault of "the lower orders".
It's always been like that.
The main stream media is owned and run by the same people, mega rich, tax dodging, non doms, and they happily join in and whip up a frenzy of dissatisfaction and positive hatred. Other "races" being top of their list, single mothers on benefits very popular, and so on.
You are a sucker for believing everything they say.
Even if everything you've read about this woman is true you are attacking the wrong targets.
You've probably also missed that in any case there is no suggestion that she is fiddling anything. She's just making the best of some cr ap decisions and probably other circumstances beyond her control.
Kids look happy and well cared for! Better off with her than in care, which would cost much much more.
