Bonkers suggestion! You really think the children of high earners need £21 a week in benefits so that they see themselves as equal to children from poorer households???
If you are a high earning household your kids are not equal to children in households claiming benefits. They are privileged. They are lucky. Why not teach your kids that??
Btw I agree that CB should be claimed according to household income and that the current system is shockingly discriminatory towards lone parents (women). I do not agree with universal monetary benefits
