Scout's right. Go back to actually giving them food some enterprising souls will still find some way to convert that to cash, I'm sure but the idea (I thought) was temporary assistance to give nourishment, not subsidizing whatever lifestyle they are choosing.
I would bet money that in the cases of children on SNAP, the food Mom and Dad (stop laughing, there might be a Dad) buy isn't actually very nutritious, despite the supplement. See the "obesity epidemic" on the news. I hate to say it, but for the most part, rich kids ain't fat.
If we are going to just hand out cash, however, I honestly don't think we need to get out panties in a bunch on how it's spent. First, .gov poking through grocery receipts is a tent that camel's nose needs to stay out of. Second, It's still a free country. People on assistance haven't actually become second class citizens, despite how infuriating the abusers are.
