The Old Adage: Waste Not, Want Not

What happened to that being the norm in the USA? No really, we didn't used to be a country of rampant consumption, in fact it used to be that the government was big into saving, food efficiency, and similar practices. Notice the notation at the bottom, "U.S. Food Administration." For those of you who don't know, as I didn't before doing a little research into it, The U.S. Food Administration was in charge of food and making sure there was enough during WWI. During WWII that was rolled in with other rationing and there wasn't a specific department for it, though most of the food rationing and propaganda came under the US Department of Agriculture. The poster Right in my mind embodies how we should be thinking, though I think use less corn would be an important addition today.
