Diversity should be thought of as a debatable means to obtain greater competency, but never as end into itself. Kate on the Florida International University bridge collapse:

950 tons on a single 174 foot span.
A concrete ROOF.

For a pedestrian walkway.

Kick in groins from a construction company project manager, from Squawker:

Leonor Flores, FIU alumna, and MCM project exec says her number one priority when building bridges is to make sure they look pretty. Nothing else matters:

What moron hired Ms Flores? Beauty is never the upmost priority, and engineering is never a matter of a single design criteria. I know local trail clubs that can, and have, built better bridges. Some lawyers are going to get rich off this case.
