"A headline that really struck me on the day of the tragedy in Bangladesh was 'Living on 38 euros a month'. That is what the people who died were being paid. This is called slave labour," the pope was quoted as saying at a private mass.
"Today in the world this slavery is being committed against something beautiful that God has given us -- the capacity to create, to work, to have dignity. How many brothers and sisters find themselves in this situation!" he said.
"There are many people who want to work but cannot. When a society is organised in a way that not everyone is given the chance to work, that society is not just," he said.
