I've never understood the taboo for saying how much you make. I've tried to avoid this taboo. When my previous employer closed the office I was in, I shared all the offers I got with a co-worker as did he. I was getting better offers, but I had more experience and neither of us felt embarrassed or insecure about it. We both ended up with pay increases at our new jobs. Companies rely on this taboo to negotiate the lowest wages possible for each employee, to the point that I know managers that made less than the people they managed, or a developer doing the same level as work as me making $48 when I was making $83, because he came in as a junior developer rather than being higher at the level he was producing at. I encouraged him to ask for $70k or get another job. He got another job at $67k. The only reason he knew he was underpaid was because I brought up the topic and shared what I was making.
