Actually no, I asked 27 people who worked with my sister, one day while I was spending some time in her workplace.
Several of these people I knew fairly well, but they pretty much fall across the spectrum of AVERAGE american. Few graduated from college, but most from high school.
The fact that the WSJ is the best selling paper means squat. More people read the comics, which are syndicated in many newspapers, than the WSJ.
There are over 280 million Americans, Floyd..how many of those have NEVER EVEN READ ANY OF THE JOURNAL?
The fact is, I tend to move around in diverse social circles, with both highly educated and minimally educated people. I don't tend to find the more uneducated ones are any worse people, though their range of conversational topics might be too limited for someone like you who thinks "many, if not most, of the posters here are beneath <you>?" Get out of your ivory tower and actually meet more people, and see what they are concerned about, not merely the ones you consider not "beneath you", before you are so staunch.
By the way, I never claimed to be average personally. I am entirely too intellectually inclined, with both the good and bad aspects of that, to be generally considered average. But I am honest, even when its brutal, and if you cannot accept that, not my problem. Everyone chooses to wear their own blinders.
I have lived, over the years, in Los Angeles, New York City, Chicago, Seattle, Houston, Tampa, Orlando, Jacksonville, Norfolk, San Diego, and assorted smaller places across the US. I have found that generally, most people do NOT have educated opinions regarding world affairs or history. Even many professionals who are highly educated within their fields.
To presume being American makes you an expert on everything is, frankly, stupid. And a reason why so many people dislike Americans who think like that, when anyone who comes to visit can see the truth. We are no inherently smarter than other folks, we just have opportunities that many do not..and that most of our own people do not even bother to maximize the potential of.
