WAIT! who is throwing stones at these people? I am actually quite shocked about it. It's actually scary that it could be that easy to get to the point of digging through a dumpster. 
Good old Yankee tradition, Dump picking. Getting a town Job at a small town dump not only has good pay but hidden perks.
June and December are bonus months for the workers, June for the weddings and stuff accidentally thrown out, Dec. for the lost things tossed mixed up with the wrapping paper. One company who sends huge trucks to service the towns has a shop that restores old appliances that they then sell at a recycling dump.
Saw on the coupon site that Monday mornings the rabid discounters would hit the dumpsters outside large apartment complexes looking for the Sunday papers and the inserts with the store coupons.
I knew a woman in NC that bought a used cash register, went out every day looking for product containers with a send in for a discount on them. She would haul all this trash home and cut out the offer from the containers and make up a phony sales receipt.
She had PO box's in everyones name in the family, I caught on when I noticed her unopened mail had MY name on it.
Dumpster diving for food is a tragedy, reminds me of story's from Germany about the former socialites in the war torn city's fighting over a cigarette butt someone had dropped in the streets. Food for the civilians at the end of the war was down to some bread and pea soup.
So we feed through Charity's the hungry of the world and we have our own people digging in garbage for food. Good Job FEMA, great job Obama, we have one heck of a good planning administration for disaster relief in our country.
