I recommend you a study on "social capital" by Pierre Bourdieu and Jean-Claude Passeron titled The inheritors. I disagree with all of the conclusions they draw and the recommendations they make but the rest of their analytical work is brillant and insightful.

Sadly there doesn't seem to be an easily accessible english translation. If you read French you should go for it, as it is arguably one of its most important and underrated work.

I found this companion/introduction to Bourdieu's work but I cannot vouch for it: https://www.amazon.com/Culture-Power-Sociology-Pierre-Bourdi...
