I couldn't give you specific figures, but as far as those benefits are concerned, you would have a situation whereby somebody's overpaid. What if that responsible party didn't realize that's where that source of income came from and they spent some of that money? Then you have to recoup that money from the government because it's owed back to you. There are instances like that when it's going to be expensive to get your money back, and there's paperwork involved, and the headache.
