Who does ignorance and want belong to from the Christmas carol?

Ignorance and Want are two children hidden beneath the robes of the Spirit of Christmas Present. At the very end of the Spirit's visit, Scrooge notices two "claws" protruding from underneath. The Spirit parts his robes to reveal the boy and girl, both of whom are in an awful condition. When Scrooge asks to whom they belong, the Spirit answers, "They are Man's." It is, however, the boy that the Spirit especially warns Scrooge against. Ignorance must be erased, the Spirit seems to say, or he spells doom for the race. When Scrooge asks if there is no refuge or resource for the children, the Spirit turns Scrooge's own Words against him. "Are there no prisons? Are there no workhouses?" These are the last Words Scrooge hears from this visitor.
