I agree that the overhead burden is insanely expensive. There's also the cruel, soul destroying experiences on both sides to account for. The staff, paranoid, treating everyone as a leech until proven not. The downtrodden, forced to prove their innocence while drowning in the bad hand life dealt them.

Another effect to consider is where do all the staff go to get new jobs? Many will find the private sector exceptionally difficult to integrate into after decades in public benefits work.
