The current customary function when a president is re-elected, is for his/her cabinet to submit their resignations. The president then makes whatever decision to keep or not keep someone in their respective office. The same practice would work here.
First, change the requirements for food stamps based on economic status ONLY If you make less than the current poverty level, you qualify, with special rules for owning any valuable property, have a reasonable saving account or financial worth. In other words, if you can afford to buy your own food, then you do NOT qualify for food stamps. Then, anyone who is currently receiving this benefit, must re-apply for it or it expires within 3 months.
There is nothing more disgusting than watching a food stamp user, get into their Lexus and drive away while chatting on their $500 iPhone.
Give the benefit to those who really need it, and stop the fraud and waste.
