"... what they did is prove conclusively that they are in fact the "rubes" ..."    Strikingly,  you find it perfectly OK to make gross generalizations about a whole class of people (and call them names), based on nothing except stereotypes and complexion.  I suspect that if anyone else used this tone with any ethnic group that didn't happen to be white or culturally European, you would immediately condemn them as poisonous bigots.  And yet here you go, without a single trace of irony.  

"... Not every blue collar worker is white, by the way ..."   LOL!  Thanks for sharing, Mom.  My own blue-collar credentials are impeccable (dad was a laborer with an 8th-grade education; I started working for wages at the age of 14).  Odds are I'm the closest thing to a genuine member of the Lumpenproletariat that you've ever met (sheeesh!)  Inlaws in my extended family have Hispanic surnames - what do you make of that??  :)  

And we never once took orders from the Koch brothers - sorry!
