I can't remember where I remember this from, but I recall a story told by an old woman who was a little girl during the depression. It wasn't a discredited viral email - I saw the woman either on TV or the Internet. Anyhoo, she told this story...
When she was old enough to walk to the store by herself, her mother gave her a few pennies to go fetch one doughnut for her and her siblings. On the walk back home, the temptation to taste it overtook her, and she took a bite... which led to her eating the entire doughnut.
She returned home and confessed to her mother, and her mother began weeping. The doughnut was to be divided as the day's food for all the children. The woman telling the story said that this was her earliest recollection of the economic realities of the depression - her mother weeping over an eaten doughnut that her other children would not have.
I suspect that whether it manifest in weeping or outrage, many people are going to be getting a reality check in regards to wanton wastefulness.
