Say one goes from receiving $500 from social security and $500 from financial need programs (welfare/foodstamps/etc). Person budgets $1,000 for food/shelter/bills.
Now there's no more social security. They only get $500 from remaining financial need programs. Person still needs another $500 to live. You're suggesting they're on their own ???? The problem will just fix itself because they can go back to work, or just get on with it and die?
