The effects of social origins and cognitive ability on educational attainment

I shy away from linking directly (or only) to academic papers, but this one strikes me as important at this time. The authors show (though, of course, this is just one study) that, even when accounting for how "smart" we start as kids, the people we are born to matters: the poverty cycle. If we want everyone to have roughly the same chances in life, we need to worry more about inequality.
