In what I consider the definitive movie version, a Muppet asks Scrooge not to yell at him, but he’s late with his mortgage payment. Given that, I’d guess some sort of moneylender/landlord combination, making his money from real estate.
Per Dickens himself, Scrooge was based in part on John Elwes. His fortune came through real estate, moneylending (though per wiki he lost a lot of money by loaning to titled noblemen who he would not ask to repay), neurotic miserliness, and investments.
Marley refers to himself as a money-changer:
From Stave 2 there’s this when Scrooge is afraid he’s slept an entire day:
So to at least some extent he invested in securities.
I vividly remember a TV interview in which Little told this eerie story. In 1963 he did an LP version titled “Scrooge and the Stars”. One of the impressions was of JFK for the Ghost of Xmas Present. The LP actually appeared in stores on November 22. And JFK had the line, straight from Dickens:
Little said they withdrew the album and re-recorded the part with another voice. However, a few albums had been sold and were still out there. Just last year I obtained an mp3 of the album.
I got it from Frank Muir on one of the reruns of “My Word!”
I wonder if Scrooge & Marley’s firm name on the London Exchange was just S&M, and if that had anything to do with how they made their money.
I’ve never heard maize said in real life, and seen it more in American sources than British. ‘Indian Corn?’ I would have assumed that meant corn. We say corn for corn and wheat for wheat.
Corn=wheat did used to be true, but hasn’t been for at least a century.
No - remember, we say shop, not store. A warehouse is a place where retail or wholesale goods are stored, not where they’re sold. There are a couple of shop chains with Warehouse as part of their name, but that’s just their name. Dictionary.com messed up. I reckon you’re right about the fried fish stand being a sideline of a main warehouse on the docks; you do see such in old pictures.
