I ask because we had a situation in Ireland just like this many years ago. It was for welfare fraud specifically and faced criticism for a few reasons. One was that the suspected levels of fraud may have been much lower than the politician was claiming. The other reason was that the cost of tackling it could likely outweigh any savings.
Sure! It creates real jobs, while also discouraging people from fucking over the system. Even if there’s zero fraud happening, auditing the system to make sure isn’t going to hurt. (Well, it won’t hurt as long as they don’t remove people that are entitled to the benefits.)
