I am not going to fully argue against these measures - I can see a need for something to be done, in certain circumstances, BUT if they put this into place, how long will it be before they drop the amount of children that low paid workers are 'allowed' to have? And where will they stop? Three? Two? One? None?
This is dangerously close to the start of an insidious process to limit the amount of children the poor can have - which, to my mind, is eugenicism.
I can see the logic of paying SOME of the income for people on benefits (Which I don't class Tax Credits as, BTW, after all it is a BUSINESS SUBSIDY to let employers pay less than a living wage to their employees) in vouchers, to ensure that the money gets spent on what it should be spent on. But the main problem with that is that a system like that will not allow for any flexibility - for example, say, the DWP may give out shoe vouchers for a cheap shoe shop like Shoe Zone - where ALL their children's shoes are an 'E' fitting. I have dc that have 'H' fitting feet - and would be unable to get an 'E' fitting shoe ON THEIR FOOT. So I either have to buy their shoes from Clarks or independent shoe shops. And for one of my DC's - his feet are so wide he has to have his boots specially made, as the NHS should be providing them, but don't now - yet the orthotist tells me he still needs them. If I was to get shoe vouchers for a £15 pair of shoes - it wouldn't go very far towards buying a £120 pair of extra-wide Piedro's.
And there is no affordable system that would allow for that amount of variation between dc. What about DC who need to be on a Gluten-free diet? You CAN get some foods on prescription - but home-made GF bread is much nicer than shop-bought. And it is MUCH more expensive to feed a dc on a GF diet than it is most dc.
It would be the lack of flexibility in a system like that that would push SOME dc into poverty. Not all, and not all families who have 5+ dc, but surely in this day and age, even pushing ONE child into poverty is unacceptable - even if their parents ARE irresponsible?
There will always be 'scroungers' in ANY country with a Welfare state. The big question is, is whether it is OK to adversely affect the genuine claimants in order to stop the 'scroungers'?
There are some people in a similar situation to me that I look at and just go WHY? People who have 4 dc like me, but have never worked, have no intention of ever working, and laugh at people like me who TRY to go out to work.
I HAVE worked in the past, and I WILL work again - I fully intend to be back at work PT when my 9mo DS3 is 3yo and gets his vouchers to make the cost of nursery less. I may not be able MEDICALLY to work FT, but that doesn't mean I can never work again. I may have a 13yo DD who still needs supervision at all times, but I am hoping that is not forever, and in 3 years time, hopefully she will be at the stage of an NT 12yo who can be left at home for a few hours after work. Right now, finding SN childcare is not happening, but that doesn't mean I will never work or pay tax again.
I don't really have the full solution to this, maybe paying TC's to the employers and making them pay a LIVING wage would help, but that in itself would cause more problems as has been mentioned upthread. However, I am of the opinion that no dc should be left below the poverty line simply because of the actions of their PARENTS. It is not their fault, they did not ASK to be born, they had no choice in the matter, so why should they suffer? And why SHOULD those who have fallen on hard times be made to stand out and be stigmatised by only having vouchers to spend rather than money like everyone else? It's a very complex issue, and I can't see ANY solution that will work for every person affected.
