Also the more qualifications and requirements you add to your social programs, the more bureaucracy is required to process, document, and enforce those qualifications.
For example, if you implement a free lunch program for all public school students in a state, you actually get to subtract out the amount of money that each school district spends dealing with reduced and free lunch program qualifications for a subset of students, all of the paperwork involved in maintaining that list and re-verifying it annually, and the system that manages their account balances at the cafeteria register.
