Jgirl,
(It suspect it was just an accidental oversight on your part, but of course, in China the Cultural Revolution did more than just beat, humiliate and damage the educated, but ended up killing about 4 - 5 million - of all classes - by most historians' accounts, all completely within the borders of China. This in addition to what happened in Vietnam, Cambodia, North Korea, etc.)
You bring up an interesting point. How did expertise and the educated class, the elite, get such a bad name? Well, I blame the elite themselves.
Prior to the West's Cultural Revolution, the elite considered it their duty to maintain the status quo (for better and worse) and to forward civilization as we knew it, for better and worse. The elite were the bulwark against the passions of the masses. The masses, therefore, were often found to be trying to "put on airs" and be "higher than their station." People dressed up, as an example, when going to Vaudeville, in the manner in which the elite dressed up to a night at the opera.
In a spasm of self-loathing, in a couple of generations all of this was overthrown. Due to the success of capitalism and the transfer of elitist manners to the masses, all that the West's Cultural Revolutionaries was trying to throw over had made the elite less so; it was a pretty good life for the average middle-class Western kid, going to college and vacationing in France.
Now, we live in perhaps the first time in history where the elite are trying to emulate the lower classes, to show their "authenticity," and they now wear jeans to the opera, and use foul language commonly, etc.
It was the educated elite in this country and the West in general which spat on the very concept of authority. Authority in all senses of the word. Not just political, religious, generational, or what have you, but the very concept of someone being an "authority" on a particular subject, whose opinion would be therefore held in higher regard on that subject than the lay person, was shot down.
We have come to this point where we can not tolerate the notion of someone or something above us. As Robert Bly puts it, "We have lost the upward gaze." We can not tolerate the very concept that there may be some kind of order or structure into which we might have to fit.
The elite are the ones who enacted an absolutely radical individualism, a kind of solipsism, in the West. The personal and subjective were given equal footing as the impersonal and objective. "Facts" as such, are now considered completely fungible, just the cynical viewpoint of the overlords trying to keep the rabble down. Literally, even testing children for mathmatics, as an example, is now considered by some as mere cultural bias towards those kids who can not do math.
Ironically, it is the elite which have torn down the concept of the elite, right when we need it most.
