Somehow the system currently incentivizing our politicians has to change. This sounds cliche but it's just a fact - monied interests control policy through graft. The law no longer applies as the law enforcement agencies have been quite obviously co-opted as well. Our 'gate-keeper' media? It is to laugh.
How to fix it? Dunno. Too many people are looking to politicians for salvation. Politicians, on the other hand, play to their constituents baser instincts - envy, hate, greed. The GOP promises law and order, return to traditional values. All deflection while the real intent is to fill their pockets.
We just saw what Washington will do to a candidate who not only refuses to play ball by the currently acceptable rules but who promises to upset the apple cart. He was beholden to no one, in his own crude way was an ideologue who simply attempted to do what he thought best for the nation as a whole. The kind of politician I thought we wanted. Both parties pulled out the stops to obliterate him.
Maybe we can find another like him without the abrasive personality. But I'm not certain they would fair any better. I truly believe nothing short of some sort of catastrophe will change things.
