The Santa Clause Unobservant parents

So this Tim Allen comedy classic opens with Tim basically killing Father Christmas (that s right isn t it? I haven t seen it for a while). Then according to the blood feud laws of the Lapland, he is then forced to assume the role of Santa Claus (the titular and hilarious clause ). Tim is surprised that Santa really exists, but he clearly does. He also is clearly shown to be solely responsible for delivering presents to the children of the world. So where the hell did their parents think those presents were coming from? Some sort of ultra expensive and never talked about government initiative?
