Who is relieved that Christmas is over at last? It's been going on for too many months now don't you think?

Admittedly, Christmas can be quite stressful, but it can also be filled with a lot of warm and friendly times. Once again, you have limited your thinking to only possible causes for who "runs" Christmas...religion or Capitalism. Maybe Christmas exists because a lot of people find it to be an excuse to party. And, yes, I'm glad it's over too!
