I think if they really wanted to reform the system stop handing out child benefits after your first 3 kids.
Those who already have more will still receive it, but any future ones will not.
You shouldn't get paid £880 a week for 7 kids and causing over crowding, this isn't trucking sub Saharan Africa.
If that's not milking the system then what is.
Also it showed that we need to protect vulnerable people more, because a lot of them are being targeted at the expense of richer people, like that recent scum bag mp Maria Miller. If they gave those benefits that mps fradulently "mistakenly" claim to poorer people instead, at least they would suffer less.
