The WSJ took the data from this study and created this graphic:
The reason that I posted the data below on how age distorted this study is simply because
this data massively overstates the degree of income mobility in the US.
It is one of the most blatant misrepresentations I have ever seen on the WSJ editorial page.
All I trying to do is show why the WSJ article is a misrepresentation because it never said a word about how aging distorts the data.
