Blindest of all, the academic Left.
In 2016, sociologist Arlie Hochschild published a wonderfully empathic study of rural Louisiana voters, trying to answer the question, why do they vote Republican against their own material interests. She steeled the question by focusing on a community that lost all their most highly valued material goods in life -- the value of their homes, their recreational environment including their hunting forests and their fishing lake -- yet continued to vote Republican knowing that their losses were the direct result of Republican policy, namely deregulation of the oil industry in Louisiana.
Hochschild provides broad and ample details of the losses, and plenty of testimonials of the victims that they fully understood that the losses were the responsibility of Republican policy. And she delves deeply into their community and its values. She also constructs a narrative, a metaphorical story, of why they distrust Democrats.
The story goes: imagine ordinary Americans are all lined up patiently and properly waiting to attain the American Dream that they can see way up the hill ahead of them, but Democrats are allowing blacks and immigrants to cut in line, cutting in front of these patient, proper Americans. That's why the Louisianans distrust the Democrats and trust the Republicans.
I finished the book feeling that Hochschild had not at all answered her initial question. Their outrage over the line-cutting story itself makes sense, but there's something wrong, something doesn't add up. The Louisianans are fully aware that the Republican policy harms them, not metaphorically or remotely or abstractly in story-land, but in reality in their face, in their pockets, in their real estate value, and the value of their material goods in life -- nature, being close to pristine nature, enjoying the beauty of nature, hunting and fishing. If they were waiting in line for the American Dream, their Republican governor took them out of the line and dumped them in a landfill of trash. They're not in line for anything in the trash heap, and they've lost everything they had and worked hard for.
Why then do they subscribe to the anti-Democratic Party story? Why don't they face up to their real-life enemy? Why make up a story to invent an enemy, when reality -- which needs no invention -- is right there in their face to complain about? (This is not unlike the Gates-Musk paradox I wrote about here and is an example of the reflexive data, and emotional data characteristic of the social sciences described here, and interactive identity creation here.)
The answer came to me from Keith Stanovich's The Bias that Divides Us, a treatment of myside bias. In his chapter on bias among academics, he points out that while liberals often complain that Republicans foolishly vote against their own material interests, liberals themselves routinely vote for wealth redistribution which is...wait for it... yup, against their own material interests.
This was an eye-opener for me. Stupid as I am, I had never recognized that professional class liberals, who are educated, even over-educated, vote in just the same foolish way as downscale, non elite Republicans. Or that material interests are not the priority of voters of any stripe. The product of the professional class myself, I had all my life failed to see this all too obvious truth.
Stanovich doesn't go so far as to say that voting against one's material interests is an essential component of professional class liberalism, but I will say so. And more: the liberal assumption that downscale Republican voters are foolish to vote against their material interests is an ignorant, closed-minded and hypocritical bias against the Republican Party, and a narrow and stupid way to understand voter preferences altogether.
And yet that was the question Hochschild set out as her project. It is the project of a professional class liberal, even, like Hochschild herself, a liberal Marxist professional.
A more useful question might be, if material interests don't motivate voters, what does?
In the context of that question, her narrative of the line to the American Dream is just an excuse, a fabrication to justify a distrust of Democrats. If the story is just an excuse, what's the underlying motivation for hating on the Democrats? Here Hochschild provides the most interesting data in her study.
There are two deep clues in her book. The community she studied is a close one. They all attend church on Sunday. They spend much of that day together communing, talking, eating together and sharing. They all see this sharing as important to one another and important to their personal and collective identity.
The other clue is that they all are reluctant to talk about black people. Hochschild herself says little about this except that they don't talk about it. She doesn't draw any conclusion about it. It is the presence-in-absence of the book.
Why do the Louisianans vote Republican? The Republican party is the party of their community identity is more important than anything else. We're a social species -- identity is social and identity is who we are. Material interests are what we sacrifice for our identity.
A student of mine pointed out in class that the Democratic party was once the party of the South. What happened?
After the Civil Rights Act, the Democratic Party became the champion of equal rights. And the Republican party became the party of white supremacy.
Why is the Republican Party the party of the Louisianan community Hochschild studied? Because it is the party of whites. The line-for-the-American-Dream story is just an excuse. The Republican Party is more harmful to them in reality, and they know it. That doesn't matter to them. Their identity is white, and the party choice follows.
There are two ways of viewing Us vs Them, in-group versus out-group. On one view, the Marxist view, held among may anthropologists, the in-group is defined by some material interest -- class interest, for example. There is another very different anthropological view, drawn from linguistics, particularly semiology, and promoted by Ruth Benedict and Culture & Personality school she founded. On her view, the definition of the in-group is purely historical and arbitrary, like the words of a language. There might be some remote, arcane motivation, but those motivations are so obscure that they are not present in the word or in-group definition.
For Louisiana whites, the Us vs Them seems to be a convergence of both arbitrary history and motivated reason (cognitive bias). The motivation is not, however, material interest. It's the historical accident of color.
Why should color make such a difference? Isn't is obvious that it's the lasting heritage of slavery? People are most entrenched in their views when they know they are wrong. The obvious wrong of holding other humans as slaves induced a lot of myside bias justifications -- "they're savages" the slave-owner insists, "we're civilizing them", "we're sending them to heaven" etc. The mere presence of a free black is an insult to their honor, since they know their enforcement of inequality is, or was and still is, so very obviously wrong. This is when people get hateful and violent over their myside bias. The wronger you know you are, the angrier you will be and more vigorously will you defend your precarious wrong, even ugly, stance. People are not interested in truth. We're interested in defending ourselves as right and good and justified.
Hochschild's study reveals that the legacy of slavery is inherited by whites. The mechanism that perpetuates it, having a heritage of ancestors involved or supporting slavery, is easy to understand.
