Problem families

[NotAllThere]

The simple problem has a simple solution - no additional benefits for you Nth child. ... I'm sure the lefties will say it's not fair on the children, as it's their parents who are unedcuated who bring them into the world and they will suffer from poverty etc. ...

Some right wingers might also say that it's not a good solution, as starving children on the streets of Britain isn't good for business.

How about no benefit with regards to children conceived while either parent is signing on? And if you can't afford to look after your children, then they'll be placed in care/adopted by richer families.

This latter part was policy in Switzerland in the 60s and 70s. It wasn't a good thing. It's also state intervention on a scale abhorrent to those of us with more conservative leanings.
