I found this to be really interesting: "The researchers were especially surprised by the way in which the companies adapted to the regulation – by slowing the growth of men’s wages, not increasing women’s."
I experienced this first hand and as a result I departed for greener pastures. Isn't diversity a great thing when it suppresses wages, no wonder all the big boys are pushing for it.
Of course, everyone who gets a competitive offer elsewhere will get a counteroffer, so this policy only applies where it’s convenient.
