(This is my closing post on the entire cursed topic, and then I promise I'll shift to something more interesting.)
In trying to figure out everything that's gone wrong, I've arrived at the conclusion that you can't fall into the trap of blaming either side exclusively: it's really the fault of both. This takes place in different ways.
Everyone is very familiar with the right-wing types, since they're just the latest iteration of neolib / neocons, clinging to a 50 yr old ideology which they are also desperate to present as new.
Now they come from the tech sector rather than manufacturing, which no longer exists in America, but it's still the same slop: endless unlimited growth (shuffling fake money around in a giant Ponzi, while we run out of actual resources), super AIs and other sci-stuff, profits over people & markets and efficiency and modern economics (screwing your own people, then the market collapses and has to be bailed out), impressive triumphs of high IQ and Faustian grandiose Germanic conquering spirit (dumping billions on useless projects that won't work, while avoiding anything beneficial), and on and on.
They're also too wordcel-y and physically awkward to come up with cool slogans, so it largely takes place on 8 hr podcasts rather than books, as everyone's attention span has declined, where both sides just hype each other up and mutually detach as much as possible from the real world rather than take an honest look at the situation.
Back in reality, we all live in this remarkably inefficient dystopia where short-term gain and getting high on fumes is the only priority, so naturally almost nothing works.
Nobody thinks of larger than the next 5 mins, and especially not the elites. So while they do that, more and more individuals simply drop out and turn to various opiates and substitutes, families and communities collapse or are never formed, the entire economic system becomes a scam, etc.
The extent of the damage is never even admitted, since all the statistics are rigged, but after decades of that sort of thing it's resulted in peak absurdity: the more the graphs and stats and numbers that are supposed to measure progress go up, the worse everything gets in reality. The discrepancy between the official story and the state of the world is so obvious, that only a literal lunatic would believe them.
This is where the left-wing types come in, ostensibly to fix things, but really in order to defend every broken result generated by the system as normal, because they are so mentally ill that everything in life that is healthy they view as evil, and vice versa. They are Neo-puritans who get off on punishing the sinful masses, but they come from a technocratic and materialist and atheistic background rather than a religious one like the original puritans did.
Their basic world-view can be summarized as: deprivation and austerity and scarcity is good akshually, and normality is evil.
This results in a number of bizarre ideas such as:
Sodomy, perverts adopting kids, loading up random dudes (including kids too) with drugs and surgeries in order to turn them into weird creepy abominations: based, and you're a bigot for just asking questions!
But normal hetero couples having kids, or taking care of cats and dogs and other pets? Contemptible, evil, unnatural desire.
Eating meat like every group on Earth, and especially hunter-gatherers, does: exploitative, cruel, wicked.
Relying on drugs, then more drugs to solve the problems created by those drugs, and supplementing the exact same minerals and vitamins originally found in meat? Progress.
Solving normal problems with normal solutions, basic curiosity, and systematic explanations: low IQ.
Coming up with a trillion graphs and studies, in order to wander around in circles in the desert for 40 years? OMG I LOVE SCIENCE.
Doing things the way your ancestors did: slave-like worship of tradition and the old days.
Reinventing the wheel (but worse), believing in magic, superstitious rituals? Also progress, believe it or not.
And finally, wanting to be surrounded by healthy normal people who speak your language and look like you: heterotoxicpatriarchalnormalitivity.
But being increasingly surrounded by mentally ill freaks, criminals, bums, and tens of thousands of random foreigners parachuted in at once by massive corporations? Multiracialpostwhitenesspostcolinial utopia!
The end result is that anyone who notices that 2 + 2 = 4 is banned, while more and more mentally ill people take up both sides of the debate, each of them contributing to the awful outcomes.
The vision both sides are selling is deranged, and one side keeps breaking more and more things, while the other side makes money by making sure they stay broken, rather than provide a meaningful fix or prevent that in the 1st place.
Setting aside left or right (I was being a little facetious with that Chomsky / Bannon pic) it's really become 'adults against insanity'.
