Bourdieu on social capital: it's not just about benefiting overall society (with denser networks), but primarily about preserving advantages among the upper class
within the upper class, it's less that everyone knows each other and more about an "extensive series of weak ties"
looking at clusters of who people know by occupation: elite occupations are the most socially exclusive
this has implications for political engagement: lower class less likely to know political elites (or really anyone who can affect the political landscape) thus feel disempowered
