The food stamps program: In an ideal policy world, would food stamps exist as a program separate from cash transfers? Probably not. But as it stands today, they are still one of the more efficient programs of the welfare state and the means-testing seems to work relatively well. And giving people food stamps — since almost everyone buys food — is almost as flexible as giving them cash. It doesn’t make sense to go after food stamps, and you can read the recent GOP push here as a sign of weakness, namely that they, beyond upholding the sequester, are unwilling to tackle the more important and more wasteful targets...See Paul Krugman too.
