If it really requires $30 for your teenager to get by on the weekend and you're only giving him $20, the difficulty may be trying to account for it, given the fact that they're basically always running a little behind. I see it in other places where the federal government is engaged. We try to hold recipients of grants or contributions to a level of accountability they really have difficulty meeting, only by virtue of the fact that they're strained in doing what we asked them to do for the money in the first place, let alone trying to keep track of it all.
I'm not saying that's the argument, but it needs to be put on the record as a consideration, because I think there is some element of that.
