Was thinking of the old oliver twist movie and thinking of how life could revert to the 18th/19th century of how they treated kids in W2. Kids who were orphans were usually taken to work house were they were forced to work under harsh and dangerous conditions. It provided shelter, food, uniform, and minimum education (minus reading and writing), however, for all intense and purposes, they were slaves and treated as such.
Also, before child labor laws, it wasn't uncommon that many children were working in very dangerous areas, they used kids to crawl in dangerous machines to clean/fix them, or crawl in small mine shafts to check if its safe, spending most of their lives bent over like this, which deformed their bodies as they grew older. Many children died this way. There are some interesting jobs that were not bad, like the iconic news boys of early new york, yelling and selling papers.
Most kids who survived on the streets survived by staying together in a semi-gang that were forced to steal to survive, or do even less pleasant things.
Just thought that kids have more uses than just arguing about whether they should be killable or not (I vote they should myself).
