Sorry, but it all comes down to money.
Let's face it: When Scrooge clung to his money (also known as being prudent, thrifty, economical and knowing the value of a dollar) he was bad. But when he spent his money on other people (also known as squandering) he was good.
What exactly were his sins (one for each link on his chain)? Was it running a money lending business in a free market, capitalist society, giving loans to people who needed help keeping their businesses afloat? Even if, apparently, they were bad risks? When his debtors asked for more time he gave it to them, even though it meant charging more interest, a legitimate business practice.
Granted, if he was engaging in usury or predatory lending that's one thing. He also underpaid Bob Cratchit and never gave him a raise. That's a poor employment practice, but obviously Bob had skills and a track record and could have found a better employer. Why didn't he? If you mistreat your employees they quit for greener pastures. Why does Scrooge get the blame for Tiny Tim being sick?
I loved the movie and it's fundamental lessons about kindness and family etc, but I've always despised the whole idea in fiction of capitalists being the bad guys. People who have money are bad unless the give it to you. To quote Big Daddy in Cat On a Hot Tin Roof, I call that "Haahpocraacy"!
We got a job.
What kind?
