If they're actually better than their coworkers, why can't they just go to a better company where the pay gap no longer matters? Is your life really going to be that much different when you make $340k instead of $370k? I can understand being upset over that extra $30k and fighting for it, but quitting your career completely?
Do you understand that the only thing I'm calling out here is how drastic and irrational a complete exit is? That's my only problem with this. I wouldn't believe someone who cited a wage gap in tech as their primary reason for leaving, because it doesn't make sense!
It's one of the most comfortable and flexible middle-class careers you can have in the modern economy, and it's arguably the most lucrative when you account for barrier of entry.
It feels like you're framing my argument as "there is no sexism in tech" or "women shouldn't complain", when that isn't my stance at all.
