Goldman Sachs, like most banks, has a page dedicated to diversity on its website. On it, chief executive Lloyd Blankfein says: “Diversity is at the very core of our ability to serve our clients well and to maximise return for our shareholders.”

The bank, however, does not look very diverse to the outside world. This was thrown into sharp relief last week when a Goldman publicity shot of Blankfein and his two chief lieutenants did the rounds on social media, in the wake of reports that the CEO will soon stand down.
