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.
Cost who, my friend? What kind of fraud? Don’t try to be cute.
For example, if someone gets $3 extra on food stamps, FFS good on them. If Musk gets millions (more, but let’s lowball it), he can rot in hell.
