Take away the electricity and the block buildings, add some coke can signs and nehi signs along with some cardboard and palm frond thatching into the building materials, and that sure looks like the Fabrica district which was across the street from the Sears Warehouse in La Habana, Cuba. That one was about 150 acres but not as clean and there were hundreds of kids who followed every vehicle "Penny Mister?" over and over. I never did figure out where they got incomes from - but adults seemed to only be present in the evenings - but children were always there. They salvaged through every trash bin for anything they could use, sell or eat. But, you know, I never saw them ever being unruly or out of hand. Like they were accustomed to that being their lot in life. My father was always doing something for their community - even when they brought a Rodeo (which was a novelty there)down, he had a whole free performance just for the people from Fabrica, including free hot dogs. He even made arrangements to give them baby chicks when they had an order cancel instead of destroying them. He would have Ernesto Tisol (Who Castro made a Secretary of Agriculture, and then shot him because crops weren't as good as he wanted-)(that was several years after we left as Castro was in the U.S going to school when we were there) go over and show them how to take care of them - even would bring them some feed from broken bags. Never had any problems for any of the employees either. Sears was well respected by them even if they couldn't be customers.
Back during the Industrial revolution in England there were “rag and bone” people...essentially the same class of individuals that made their living from the refuse of cities.
They are the ultimate of recyclers.
