It's hard to get into a position where you get money for nothing. I'd gladly tell you exactly how to do it, but unfortunately I am just as lazy.

Maybe try feudalism, though.

My peasants do net fairly sizable tax revenue (largely in sheep, some gold as well) but I would hardly call that “passive”, what with all the galloping around the countryside with my pikemen and all!
