Professional service firms and the manufacturing of the corporate nobility

Global professional service firms (GPSFs) are key actors in contemporary capitalism. They (co-) produce and disseminate new business practices, linking firms, sectors, and countries, integrating them into a global system. We examine a second, less studied function of these firms: underpinning capitalism's status hierarchies. We ask whether these firms have emerged as producers of a new corporate nobility-as an extension of elite universities, and as a stepping stone in the selection and promotion of top executives. Focusing on the US, we ask: do global professional service firms merely amplify the credentials of elite universities, or can they compensate for an absence of an elite education in the careers of US top managers? and do professional service firms equip future top managers with specific expertise or merely with symbolic capital? Based on a sample of 2,610 top executive managers from leading American firms in 2005 and 2018, we study the role law, consulting, or audit firms played in their careers. Using multinomial regression analyses, we find that the career function of GPSFs varies: consulting firms amplify existing status and enhance the symbolic capital of alumni, aiding their ascent to the most prestigious jobs in US top firms. In contrast, top managers leverage audit firm roles to compensate for a non-elite background, yet then tend to be channelled into narrow, specialist roles in top management. We relate these results to Bourdieu's state nobility analysis and propose an augmented typology of these firms at the heart of contemporary capitalism.
