How do they represent us?

How can it be that someone that represents me can do things I myself can not do.

Let's say I represent you, and I tell you what you must do, and may not do, and must pay for.. And not only that I also do that with all the other people (in your name). Isn't that kind of strange?
"They serve us" is another sentence that does not make sense at all. Someone that serves you does not boss you around and punish you if you disobey. That is not a servant but a master, and you serve the master.

edit I believe making good changes and choices is up to me, to appoint a master that makes everyone (including me) make the good changes and choices for them by forcing them (and me)
I'm sorry but that idea sounds very strange to me. I believe that I can not force my opinion or ideology onto someone else, with violence via the political religion and pretend that than the world would be a better place for it.

That's how I see it anyway.
