1)there is no such place where the people who run the government are "good" people
you dont get that far ahead in politics without being a bastard
the hope one should have when voting for someone is that in the big picture, they would end up doing more good then harm
2)the advantage of the democratic system is that if someone gets voted into office and then backstabs the people who voted for them
they would not get re-elected because of it
complaining is fine and protesting is fine, because these methods show the people in charge that the public is displeased with their actions and that their future in politics is in jeopardy
but once you let "the people" run the country, you make it impossible for the country to actually work
