That does seem super weak sauce. Also, the "striking" 6.2% included 2008, who's to say that the even among the 1.2 X median people, that the economic hurt wasn't enough to explain the delta there?
120% of the median income is not "rich" in this day and age
Hmm, it's above the median, it is well off. But yes, it isn't well off enough to be sheltered from the effects of the great recession, I agree.
This does not make much sense how the author derives the 6.2% figure and then says its 1.2%, nor does a 1.2% gain over a 3-year period seem like much.
