I presume you are from Spain, which indeed is one of the top countries in the Global Gender Gap Index [1] but its unadjusted gender pay gap still sits at 11.9% (2019 provisional) [2]. Yes it's called "unadjusted" for a reason (gender pay gap is a broad phenomenon and can't be described with a single statistics and that's why we have the Index) but it is far from "non-existant".
