It rings a lot of alarm bells for me, but the alarm is about the absurdity of government policy. Let's take one item as an example: sugar. The federal government has an import quota/tariff regime on sugar which causes sugar prices to rise, meaning it takes more money for consumers to buy their groceries. So in response, the government issues SNAP cards to people so that they can buy the groceries at prices artificially inflated by the government.
On top of that, the government also establishes mandates for corn ethanol usage in energy production. While noble in its intent, it actually consumes more energy to produce the ethanol than it would just to sell the gas used in its production directly to the consumers. So all of that wasted corn again drives up the price of groceries.
On the municipal level, you've also got city councils that refuse to allow low-price retailers from entering the market. That means people either need to use more resources to get to the store or pay inflated prices at mom-and-pop shops.
Remove those restrictions and a great number of people probably wouldn't need to be on the program anymore.
