I walked around my neighborhood today, there are several houses under construction. The framing and roofing crews are staffed entirely by hardy people of only one gender and with little ethnic diversity. I sometimes watch professional sports, in particular basketball. There is very, very little diversity. My son is in his first year of teaching elementary school. He tells me he is almost alone in the school, gender-wise. I think this is a very complex topic, with lots of nuances.
