The "educated class", whatever that is, are usually well educated people who have no clue what common sense is and are completely out of touch on how things work in the real world. I'm trying to be nice but most people I know would refer to them as "educated idiots".
But being Educated allows you to make comebacks like:
"Common sense is nothing more than a deposit of prejudices laid down by the mind before you reach eighteen." - Albert Einstein.
Though I also like
"There's nothing more unreal than the 'real' world"
