Well, the Federative Republic of Brazil is a democratic republic, with elections for their president every four years, so that does imply the average Brazilian has a little bit of power that is foreign from the US perspective. (If you buy this whole democracy thing, you might think that's good!)
I wonder if a restoration to monarchies would encourage agencies of the crown to keep their spying to other royal and powerful persons, since then the average subject would indeed have no power.
Would you be happy to have the government of a random country, say Russia, Brazil, Albania or whereever, reading your emails?
