Equal pay for women isn't a movement. Modern feminism is the movement, and there this quote becomes relevant:

> Mass movements that are good at what they do make previously content individuals frustrated and further frustrate their adherents while pretending to advance the movement. This means that the strongest mass movements are inevitably going to be the ones that are the best at not delivering the goods.

Equal pay for equal work is pretty much achieved and the so-called gender wage gap is extremely misleadingly used to foster frustration.
