Less lean than it might be, love. I suspect if people are willing and able to set themselves up with comfortable quarters, they can get through with their five wishes per day, so long as they don't get to extravagant. Indeed, if they are smart enough to make a big pot of bean soup it will last them for days.
You can do quite a lot with five intelligently chosen "make-wishes" a day.
