Ok. Here is an article that claims something in the headline and then repeats it many times through out the text. In all that clutter and fear mongering; claims of how much worse things are in the american society, the proof is the new "research"- if parents education level correlates well with the child's! Wow.. never thought that could be true.. The only "new" thing seems to be that the correlation coefficient is slightly higher. 0.1 higher.. What does that mean? I am not sure. They define educational mobility as a proxy for social mobility. By that definition any non negative correlation of education achievement between generations implies increasing social inequality. They bring up this statistic of "20% of middle fifth will rise to the top fifth" I am not sure whether that is bad. Naively I would expect exactly that to happen in an unbiased system without inequality. I guess I am saying, color me confused.
