This cynicism is pernicious. There are plenty of people, on both ends of the political spectrum, who seek public office in order to do things which they view as for the greater good. On the right it is things like criminalizing abortion. On the left it is things like preventing catastrophic climate change. They may barter votes or bend their positions in the name of incrementalism or long-term strategy, but it is the rare politician that is 100% corrupt, seeking office so as to sell their authority for personal gain. Believing this, that all politicians are purely corrupt, and arguing that others should believe it, is to facilitate corruption, not fight it.
