The system seems to assume that if you are working for minimum wage you must be incapable, in some way, of getting and maintaining a better paying job. I don't know.
The welfare system as a whole needs to be restructured. My girlfriend works retail and has told me that she has to bite her tongue each time someone comes in and gets a 20oz soda and a small bag of chips then swipes their welfare card. 20oz sodas, at least here, are as much or more than an entire 2 liter.
I use to think that drug testing should be required, randomized or whatever, to get welfare, too. But a friend recently pointed out that while it would help the system by stopping leeches it would more than likely put child services into action. Basically putting the burden of caring for the kids on the system... but in many cases the kids would be better off (imho).
