The job of making clothes is the best job available to these people. If it wasn’t, they would select another job.
When Babe Ruth was a child, he worked making clothes at the St. Mary’s Industrial School for Boys. The factory he worked at made enough money to support the orphanage. He wasn’t an orphan, but rather an incorrigible child, placed there by his parents.
Certainly it wouldn’t be better if the orphans died, right?
They'd better get on with it, and decrease the surplus population. /Dickens
