For many children, unfortunately they wouldn't benefit from an increase. I'm not tarring everyone with the same brush, as I had a major circumstance change in my life so know how difficult things can be, but it's not wrong to suggest that many people will choose to spend an increase in money on themselves rather than their children. Drugs, alcohol, cigarettes, whatever else. Again, not everyone, no, but many.
I don't think this will miraculously resolve child poverty. I didn't think I'd ever say this because I was outraged at PIP potentially becoming vouchers, but if child benefit needs to go to the cost of raising a child, perhaps it should be given in vouchers that can only be spent on food and nappies and not anything you choose. The genuine people who need the money for their children would surely accept this?
As a teacher, I've seen many children living in various states of deprivation and neglect. The extra money would not have been spent on those children.
Also, CMA needs a massive, proper overhaul. There are children living in deprivation due to absent fathers refusing to pay, and it's time this was taken more seriously.
