I always use plumbing as an example. You never hear about that being not diverse enough. Look, I'm all for equal pay, but I didn't see those ladies in my classroom 10-15 years ago. Only after it became "cool" to be a nerd, seeing that there is money to be made being a nerd, and realizing that living in a major city can't be subsidized by whatever they chose to study, did they start hammering on about this.

Equal pay will be very difficult to enforce unless you make salaries public. I can assure you that among your peers there are plenty of differences in compensation.
