I guess that is my experience, also. One of the reasons I left Cambridge was because I found the snobbery alien and slightly revolting. People who go to Philips Andover and then onto Harvard may be liberal in their politics but are very neo-con in their classism, even if they didn't start out that way. I don't remember what essay it was, but I vaguely remember PG writing about people in Boston trying to become "Thurston Howell III" and this unfortunately transfered over to much of Cambridge.
