Michael - well, yes, it would be helpful to have better models of 'regime transitions' among various forms of government.
However, I think it's very important not to be naive about the rather narrow range of types of hegemonic regimes that we live under. To a first approximation, all functional nation-states in the world are quasi-meritocratic, semi-hereditary oligarchies run by elites who tend to be richer, more powerful, better educated, and more virtue-signally than the common folks they rule over. This describes how things actually work in the US, UK, Germany, China, India, Saudi Arabia, Russia, Nigeria, Brazil, and virtually everywhere.
In each case, the oligarchic elites use a combination of hard power and soft power to control their societies, including military and police power, economic control, digital surveillance, 'public education' and propaganda.
This is equally true in the US and in China, for example. To call one a 'liberal democracy' and the other an 'authoritarian regime' strikes me a a fundamental misunderstanding of the nature of political power in the 21st century. In each society, the oligarchic elites nudge, shape, and control public sentiment through 'engineering consent', using a combination of state propaganda (e.g. public education, press conferences, state media), corporate media (e.g. 'news', talk shows, journalism), state surveillance (e.g. China's Ministry of State Security; America's NSA, FBI, CIA, etc), and the deep state's stigmatization, criminalization, and demonization of various forms of dissent (e.g. crackdowns on Uyghurs or Falun Gong in China; crackdowns on 'Christian nationalists', 'white supremacists', and 'traitors' (e.g. Edward Snowden, Julian Assange) in the US).
For example, if you talk with behavioral and social scientists in the US versus China, they will mention all kinds of topics and truths that are taboo to discuss or to publish about -- topics that would be career suicide to study. The list of scientific taboos is, in my experience, shorter in China than in the US -- although the specific tactics for social control of academic research are somewhat different. In China, each university has a number of a Chinese Communist Party political officers overseeing teaching and research, whereas in the US, each university has a number of Diversity, Equity and Inclusion political officers (almost 100% from the Democratic Party) overseeing teaching and research. Their powers of censorship, ostracism, and control are roughly comparable, but in each society, their hegemonic presence is taken for granted.
Related to your last paragraph, what do you think about Have epistemic conditions always been this bad? In other words, was there a time when the US wasn't like this?
PS: as always, for anyone who's disagree-voted with this, I'd value knowing what exactly you disagree with.
Thank you for challenging the question's assumption, Mr. Miller. Your points notwithstanding, I think you under-appreciate what we have, even though it could have been much better. I hope the tools that I envision would someday help clarify convincingly why not all regimes are essentially the same for human well-being.
