I like to roam but I’ll always stay home,
He likes to travel but stays in home,
He leaves a silver track,
If you carried what he could carry with the way he moved,
You’d break your neck and back.
What is he?
For now I must stay under the man who made me,
but when he dies I'll be as powerful as he.
They will watch and listen to what I say,
then some of their money to me they'll pay.
Who am I?
