Ebenezer Scrooge: I'm light as a feather! Merry as a schoolboy!
Question: What is Mr. Scrooge's business exactly, and what does Bob Cratchit do?
Answer: Mr. Scrooge is a moneylender and Bob is his clerk. Moneylendering is different than something like a bank loan because interest rates are much steeper and usually the last resort for poor people who can't get bank loans. In essence he's a loan shark.
