I've been pondering whether tuition-free university education for everyone is a worthwhile ideal (I doubt it). However, some people claim that such opportunities are essential to prevent the economic division of our society into "haves and have-nots". One of the favorite statistics offered by this crowd is the income difference between people with degrees and those without. Any educated person should recognize that such statistics are just the starting point for deciding what the value of a degree is (i.e. correlation is not causation). The obvious considerations is that people who complete college tend to have been born with more opportunities in their life (colleges select for motivated people from higher SES groups), and that these are surely contributing to the income differences, independent of actually attending college. There is also the feature of "indentured servitude" resulting from college debt -- the graduates HAVE to work hard to cover their expenses.
Anyway, I found one good discussion of what the value may be (though it isn't a proper analysis of the factors involved). For the most part it provides recommendations for books and reports looking at the issue.
Something more for me to read.
