When I started working in financial services in 2000, what shocked me was just how diverse the traders were. There were some people from rich families, some working class (I particularly remember one who had previously been running a market stall).

Turns out that capital markets have a great metric for ranking people without discrimination: how much profit they can make by managing their risk.

Ironically, the worst places I've seen for discrimination is in the public sector. They seem to see it as a virtue to promote people of their favoured race or sex/gender.

When the results aren't satisfying, change the metrics?
