People you've never met or spent any time alone with basically make your life better super frequently. Medical scientists developing new treatments, engineers coming up with better/more efficient/safer alternatives, state and local governments and councils maintaining services, etc.

If you've never met or contacted your representatives, that's likely by your own choice. They generally make themselves fairly available to some degree.

Electing a random citizen of my country instead of the current leader would make lives of people all around the globe better in mere months, no magic required.
