Here is my annual letter, sent in the very unlikely but still possible case that you actually exist. As I state every year, please consider changing careers. I suggest either taking over the post office of every country in the world, or perhaps running a spy agency, or founding a year-round toy manufacturing center. As it stands, you are wasting your life.
Your current vocation giving gifts to the children of the world once a year frankly creates more harm than good. It certainly sounds like a noble mission. However, in execution, there are severe limitations. You favor families of the western hemisphere, mostly of a Christian heritage, and of those primarily the wealthy ones. Speaking candidly, you're a right-wing capitalist Bible nut, and I fear you are fanning flames of jealousy and partisan hate.
But I'm not here to lecture. Your politics and religious views are your own. Besides, you're clearly a man of enormous talents and I think you could better help the world while also still honoring your child-centered consumerist moral agenda.
The ability to visit every home in the world on a single night means you could easily take over the post offices of every single country on Earth and improve it. I'm sure I don't need to remind you the value to society of a well-operating information infrastructure (Lewis Mumford's theories of urban development, etc). With your help, you could improve communication among citizens and businesses of all nations overnight. We could see a bump in the world economy similar to that of the early '90s after e-mail became prevalent. Even if you only wanted to deliver to kids: it'd be weird, but still a help.
