Does this means that santa is a slave master to the elfs?
If they are *naughty* and not helping they get a coal in presents and their family is pretty much .... well naughty from that point on. And then they can only work in coal mine. To get a coal for naughty kids.
Now if we translate this into real life slavery:
Some guy has some slaves. If the slave does something bad they lose a *finger* for example. This also demoralize and destroy their family and friends (if they have it).
Or in other words...the slave gets a life treating job. For example....geting a sulfur from a vulcano.
What do you think? Are santas elfs slaves or free?
