This question is much more complicated than it seems. Are there mental health issues? Are they trying to work? Is it economical for them to work (since childcare is so expensive)?
If they are looking for work and are unsuccessful, that is one isse. If there are mental health issues that they are not getting treated, then it is a different issue. If they are just lazy and want to use the system, I would have a huge problem with that. Eventually, if they were lazy, I would probably leave (although if they were that lazy, there would probably a whole host of other issues).
