Do you think Ebeneezer Scrooge had monopsony power over Bob Cratchett?
Do you think Bob Cratchett was forced to work for Scrooge?
Do you think Bob Cratchett had any other options available to him.... in London?
If you think Cratchett probably had other options available, why the heck did he keep working for Scrooge if Scrooge was such a .... Scrooge?
And if Scrooge was paying Cratchett just what Cratchett was worth on the market, what any other employer would pay, why did the ghosts visit Scrooge and warn him to reform? Do you think those ghosts visited all the other potential employers of Cratchett who didn't offer him any better job than Scrooge did?
If Scrooge was paying Cratchett the market wage, I'm not persuaded he was such a bad guy.
And if the business mores of the time made it impossible or extremely costly for Cratchett to shop around for a better job, then maybe we should be grateful for increased labour market competition and job mobility, not for Christmas ghosts.
Anyway, Merry Christmas, and "God bless us, everyone."
Update: Steve Landsburg defends Scrooge from a different perspective here.
