Now I realize it's part of human nature to try and get as much as possible for as little as possible, but this takes it way too far.
You must be really daft if can you look at a bunch of stats like "women are paid 30% less than men" and then tell yourself "YES! this is a problem that I completely understand, I understand everything about this and what these people say is exactly what happens in the real world, we have to fix this".
What the hell does "as assertive as men" even mean. Is it some caricature of a man stomping his boss' desk to establish dominance? You're either assertive naturally or you're not, this applies to men or women. Fakes are easily spotted and ignored. Socially withdrawn/inept people or autistic people constantly draw the short straws when negotiating because there's no chance for them to be even close to remotely assertive even though in a STUDYYYYY the "scientists" could claim that "they were as assertive as others" just because they tried (unsuccessfully — a detail so easy to omit/ignore). You don't just go "ok now I'm going to be ASSERTIVE" and suddenly have everyone go your way, if you haven't developed that ability since childhood (or at least for a damn while), at which point you're using it by default.
Jfc, we live too relaxed lives, we have no problems so we invent some.
