Every Single Parent Matters?

From the AHED Press Release on the matter of the proposed changes in the benefits system:

"The UK Government has made it clear they see no value in parenting and would rather see mums and dads out flippping burgers on the minimum wage, topped up with tax credits, child care subsidies and housing benefits, than caring for their own children. This will of course cost the public purse far more than providing the safety net of Income Support for families, especially where children have special needs."

From a purely fiscal point of view, that seems sound. Of course, it's impossible to factor in the hidden costs of children raised without parents, but they will be there without a doubt.
