"Davos has a way of separating even the global “elite” into strata. Participants’ relative importance is made known through the colour and design of their name badge. The hierarchy of attendees is also enumerated, with more nuance, in WEF’s databases. Participants are put into categories numbered from one to seven—an indication, of sorts, of how senior or perhaps important a delegate is to the business world"
