Government is supposed to be of, by, and for the people via democracy, but the problem is that the choices are picked by big money and lobbyists. Also, a large portion of the electorate are either woefully uninformed or misinformed and are easily deceived and manipulated into voting against their own interests.
I can agree with that. And because it is so, it would be best, if power would not be centralized in such way. Power always corrupts humans. It is really like in the Lord of the Rings. When human gets much power, it is dangerous. Also, as you say, humans are easily manipulated and not well informed. It would be best, if people would have power only for their own life, because then they can't cause much damage.
If people decide only about their own life, it would be truly democratic and then different opinions and needs would be heard equally. Always when the power is transferred to someone, it weakens democracy and persons position and possibility to be heard of.
