I support lifting the cap for working families. I feel terribly for situations where sometimes both parents work and they still can't make ends meet. They deserve support.
What I don't agree with is more money where both parents are out of work. Give them vouchers, food stamps, access to education and support (Surestart should be brought back) but not just more money to spend unaccountably. That shouldn't be controversial but I'm sure it would be trampling on someone's human rights.
And I completely agree that absent, non-paying fathers should be made to contribute by law or face penalties, including prison.
