This is wrong and ignorant of how we select elected representatives. They have no incentive to do “what is right” and all of the incentives to do “what is popular”. The representatives who stood up against the Patriot Act, the surveillance state, “you’re either with us or either the terrorists”, etc were unable to hold any control in Congress.
The reason we have stereotypes of politicians as lying, greasy, corrupt used car salesmen is because their incentives align with those qualities.
I am exclusively discussing the _is_, not the _ought_ (which is where I would agree with you)
I also don‘t think mine is a widely unpopular opinion either. That scholars of democracy and human rights agree that a democracy should not be able to vote them selves into a dictatorship, that human rights are worth something more than what can be ousted by a popular demand. So I don’t think this is an unreasonable historical framework, from which I judge the actors of this history of.
