Nowhere. It was created by FDR through the Social Security Act written by congress into law.
So I ask you again, after creating the law to help people who really NEED help, where does the government get off telling people they can only use it to buy this or that food, when none of their restrictions or exclusions make a bit of difference?
Little/no impact on their health (for whatever THAT is worth), and certainly no saving to the government!
And since we all rely on various government services, how will you be if the government decides to start telling EVERYONE what they can have, buy and eat?
DON'T YOU UNDERSTAND? I don't want the government having that kind of power over anyone. For once they have it over a few, they can only try to have over more.
