John,

However, while all that is an interesting aside, it is not the premise of my post which is the obfuscation of what appears to be (according to this answer) that there is not not much of a difference, if any, between very rich and middle class.

That is what I understood as well: the difference is statistically relevant, but slight. I do not see any obfuscation here; it may lie in the context though.

Willful obfuscation of correct facts is quite a common pest. Misrepresenting the facts is another one. Fuzzy fact-finding, such as "Do you think the rich deserve their wealth?" is another one. Lack of intrinsic logic (which I mistook as your accusation) is another one. Lack of wisdom yet another one (as in Lizzie's example). Getting one's language wrong is quite a different subject.

Many reasons to go "huh?". Journalists, teachers, judges, and Mudcatters should be able to expose and neutralize all such pests, since they have a mandate for the common good. Too often they do not live up to their responsibility ...
