What would the thomas theorem suggest about the legitimacy of santa Claus?

The Thomas theorem posits that "if men define situations as real, they are real in their consequences." Applying this to Santa Claus, one could argue that the belief in Santa creates a meaningful experience for children and families during the holiday season, making him "real" in the sense of the joy, tradition, and cultural significance he embodies. While Santa Claus may not exist in a literal sense, the positive impact of the belief can be considered legitimate within the context of social and emotional experiences.
