Ask any grocery clerk; it’s very common to see someone use SNAP to buy the listed items and then immediately afterwards spend their cash on the other things. Funds are fungible, after all.
All of which isn’t really a big deal, tbh. However the program is so large and the hoverment abandoning the purchasing power they could have if they dictated more the “buyables” is a regret. They could have “WIC” stamps on foods that are not only healthy but actively good, low in sugars, etc.
Why is this at all surprising? SNAP doesn't cover anything non-food, like cleaning supplies; people still need toilet paper and soap.
It's called "Supplemental Nutrition Assistance Program". "Supplemental" seems to perfectly describe that behavior.
But that's an acceptable price, imo. You will always have scofflaws and people who just want to be fat, but that's part of the price of a society.
