It's a guess rather than an assumption -- I wouldn't be astonished if it turned out to be a wrong guess -- but there was a reason for it: some of the comment seemed to require "bottom" to be about wealth, and other bits seemed to require it to be about behaviour. But, again, I could very well be wrong. Would you care to suggest a concrete definition of "bottom quintile" according to which the claims made by black6 are true?
