That guy is a pretty great example of what went wrong and can’t see it. He is a former Rob Portman economist, current Manhattan Institute fellow and has Ukrainian and pride flags in his bio.
He appeals to approximately no one in the electorate except some east coast moderate dems and he is having a sad about it.
He is of course correct that politics is a spectacle but he appeals back to some bygone era when the “adults” and “experts” were left to run the world. While it is true that the forces that have arisen and taken center stage have de-stabilized the order, that order previously was not a force for good for many people and has increasingly become incapable of addressing concerns of working people.
Inequality and the breakdown of faith in the institutions and elites that are running things are enormous problems. While he is looking at electoral politics and “the crazies” he should also pause to consider whether things like people seeing Supreme Court justices openly flaunt ethics rules that essentially every other worker public or private cannot violate is driving people to put that rage somewhere. It is not going to magically come out as a coherent critique of the system, just like when I locked the keys in the car my dad didn’t calmly explain that was dumb.
