Dennis,
I agree with all your points; I thought the news report was a nice
example related to regression to the mean and of attempting to prop
up a (nearly certainly true) statement using invalid statistics -
note that the report appears to refer to the *current* top & bottom
10% and what their % income increments had been, rather then (say)
the top & bottom 10% five years ago and their *subsequent* % increments.
