Unbelieveable some of the things you're asking SANTA for.
Are you serious?
Santa, even if 'real', delivers object presents. He doesn't do wishes like a "GOD" would.
Don't confuse the two, because symbolically there is a difference between them.
With that said- IF Santa was real, for conversational purposes, I would ask him to deliver each child the child's favorite toy.
It wouldn't matter what it is or where it comes from- but EVERY child should receive their most favorite requested toy on Christmas day.
That's about it.
