Never thought I'd see the day but, hell yes! Backbencher Harriet Baldwin has mooted the idea that child tax credits should be capped at 4 children for familes that have no wage-earner. About time too, I've seen several instances where a families tax credits award is greater than my annual wage! Unless there are exceptional circumstances, eg you had 2 kids and then had a set of triplets I think that's the way forward. Too many kids think that a life on benefits is an acceptable career choice, time for a change!
