2 adults and 4 children is nit the norm though :/
Even with 3 kids they would be getting around the benefit capped amount of 26k, especially if their rent is more than £180 per week.
And housing benefit going straight to the landlord
The working person also has to pay rent or mortgage out of their income too - their housing doesn't come for free just because they are working.
I'm a big fan of the benefit system whether it be to support people in times of unexpected circumstances or to top up low wages. But it really gets my goat when people think 'oh but you don't need child benefit because you earn £50k, but I need it because I only get unemployment benefits'. When the reality is that disposable income might not be much different and both sets of people might equally need the child benefit to buy shoes or food for the children.
I think higher rate tax payer would be more supportive of the benefits system if they felt fairly treated and dint end up worse off financially for working (which can be the case once you factor in childcare and commuting costs). It's very difficult for a family who work many many hours and forego precious time with their children to feel happy about having their child benefit removed when the couple down the street don't work and have the same disposable income (or more in a minority of cases).
My household is not affected by the child benefit means testing so I have no reason to feel resentful of anybody. I just think the whole situation is a farce and set to breed resentment.
