I'm a person with XY chromosones (a man, for I don't think anyone on the thread is desperate to resort to such cumbersome language IRL) and I also believe the gender pay gap, while real, is massively overstated and simplified. I remember discussing it with a friend last year - the headline was "woman earn 22% less than a man" - which is technically true. However, when drilled down to same job, same experience, same qualifications etc... the "pay gap" was only 6% IIRC. Which is much less media-worthy than a headline figure in the double digits.
As it is, once someone receives the minimum wage, or the correct amount in a union-negotiated wage structure, I don't really care what people earn. It's an individually-negotiated contract. If you are willing to accept less, or don't know your worth, that is on you, not "the patriarchy", nor the business which is trying to keep costs (such as salaries) to a minimum.
