I’m coming in late to this, but I agree with Damon@#15. This is not really a bad idea. As JMH@#60 mentions, a lot of us were taught how to use leftovers in planning other meals in the week (I was a bachelor for some time before I married) by our mothers. We were taught rudimentary sanitation in food preparation. We were taught how to plan meals in the most cost effective manner. I challenge you, fellow commenters, to say where today’s young families are getting this education/advice. So, if proper food management and food preparation for many families is a problem, that once solved saves the individual families money, reduces the amount of waste destined to rot in land fills (although it may eventually produce methane for heating), reduces the number of trucks required to haul waste, et cetera, et cetera, how would YOU propose solving these problems? Not all “nanny state” solutions are bad, they just need to be examined closely.
