I agree with the OP article, but it does not explain root causes.
I’ve felt for decades, from the Vietnam War on, that we have been lied to by the media. What rightwingers call FAKE NEWS today I always saw as “manufactured consent,” insidious propaganda, and collective cultural obsessions — lies told by both parties.
But that was still “democracy.” The U.S. still seemed for most of us a truly “exceptional” Republic doing its thing to save the world from communism. Fighting to make the world “safe for democracy.” Always supposedly improving its own democracy. Of course ours was already really at the same time an evolving international financial empire, what rightwingers today call “globalizing capitalism” — something that would inevitably trash American workers. But it sure seemed to have its strong points too. And the myths it told itself were believed by many.
Now the rot has spread internally to such an extent that even the average Joe sees the lies (from all parties). He just struggles to believe half of the lies, and seeks out “the lesser evil.” In a way that makes sense.
Our society is no longer becoming more democratic. It is not spreading freedom abroad either. In Trump it has accepted a risible demagogue reminiscent of Mussolini, promising to “drain the swamp” and MAGA. Americans want to go backwards to a simpler time, and they refuse to give up the perquisites of their empire even when it is hurting them.
Trump’s pathetic narcissism suits many Americans who want to live in the bubble of the past. Democrats lie as do all politicians, and they have no clear road forward. But Trump’s lies look backwards. They are the bald faced, absurd lies of a cranky old man, who has selfishly promoted himself all his life. He is a creature of the media, a terrible administrator, not a man capable of working with others, a child of privilege who never grew up, a man with a megalomaniacal ego, who needs to be worshipped. He is thus a very poor leader for a country with nuclear weapons facing multiple real challenges.
