Child benefit for one child only
Families should get much more help with the first child. They should get much less help with subsequent children. Having a large family is a lifestyle choice and should not be subsidised by the taxpayer. Of course this is only fair if contraception is free, and easily available.
Why does this idea matter?
The benefit system encourages large families, especially for those that can least afford to pay for them. This is madness in a country which is already overpopulated.
The main cost to a family when they have children is the fact that one of the partners has to give up work. There is no similar cost for any additional children.
