Jeez, I wish we could just retire the quote that titles this thread. Perhaps replace it with this one:

"Disdain for the less educated is the last acceptable prejudice."

Survey research bears out what many working-class voters intuit: At a time when racism and sexism are out of favor (discredited though not eliminated), credentialism is the last acceptable prejudice.

In the United States and Europe, disdain for the less educated is more pronounced, or at least more readily acknowledged, than prejudice against other disfavored groups. In a series of surveys conducted in the United States, Britain, the Netherlands and Belgium, a team of social psychologists led by Toon Kuppens found that college-educated respondents had more bias against less-educated people than they did against other disfavored groups. The researchers surveyed attitudes toward a range of people who are typically victims of discrimination. In Europe, this list included Muslims and people who are poor, obese, blind and less educated; in the United States, the list also included African-Americans and the working class. Of all these groups, the poorly educated were disliked most of all.

Beyond revealing the disparaging views that college-educated elites have of less-educated people, the study also found that elites are unembarrassed by this prejudice. They may denounce racism and sexism, but they are unapologetic about their negative attitudes toward the less educated.

By the 2000s, citizens without a college degree were not only looked down upon; in the United States and Western Europe, they were also virtually absent from elective office. In the U.S. Congress, 95 percent of House members and 100 percent of senators are college graduates. The credentialed few govern the uncredentialed many.

What is the implication behind repeating Trump's line about the poorly educated as if it were a negative thing to say? Do the poorly educated not deserve to be 'loved' - or respected or have their needs addressed? Is a politician who is more beloved by the better educated than the less educated somehow better than one for whom that's reversed?

Part of the main differences between working-class voters and the current Left coalition is attitudes towards Elites - which is not just about wealth, but about credentials as a form of Elite status. That's part of why universities are in trouble, and why waving Trump's quote about the "poorly educated" as if it reflected poorly on him is going to make it harder for the Democrats to win back the working class.
