From PEA Soup, a blog devoted to policy, ethics, and academia:

Many people teach their small children the myth of Santa Claus: that a magical being who lives at the North Pole brings presents on Christmas Eve. Secondary aspects of the myth are that whether one receives presents is a function of one’s behavior, and that you can communicate with Santa about your preferences. Not only parents, but retail establishments and (I have recently discovered) public schools collude in perpetuating this myth among children of a certain age.

Perpetuating the Santa myth has at least these moral reasons against it:

1. It involves a lot of lying and deception practiced on credulous people.
2. It tends to foster greed in children and contributes to their false impression that one’s happiness is determined by one’s material possessions.
3. In telling children that the quantity and quality of one’s gifts are a function of one’s behavior, when actually they are a function of one’s socio-economic standing and parental temperament, it induces moral complacency in well-off children and false feelings of moral inferiority in less well-off children.

It seems to me that these reasons are sufficient to show that perpetuating the Santa myth is immoral. Most of America strongly disagrees with me on this point. I would be interested to know what the professionals at PEA Soup think.

Lying to children about Santa is just one of the many ways in which parents feel no compunctions about manipulating their children rather than treating them as persons. The only “good” thing about this manipulation is that it is supposedly for the benefit of the child, though that is debatable. One problem with the Santa myth not mentioned above is that the associated manipulation and lies is indicative of a broader pattern of manipulation and lies.
