In the US, discussing salary with coworkers is protected speech. It helps people find out if they are being underpaid or unfairly discriminated against. I always share my salary information when asked and I think it's important to do so.
My salary is not indicative of my net worth. I could have a 7 figure salary and be drowning in debt, or make 75K and be doing fairly well because of responsible choices.
I dislike the stigma of discussing salaries, and believe that it's propagated by companies to dissuade workers from getting fair salaries.
In Sweden it's stigmatized because of "jantelagen" (a set of written unwritten social rules, basically, don't think you're better than anyone else and don't boast). For example I've got a high paying job as a software developer, so talking to my unioned electrician friend who makes significantly less about their $120 salary bumps is kind of awkward. If he found out how much I make I'm pretty sure there's a chance he'd do talking to me for a while.
But I'd like to say I'm staying humble still. I was about to study to be an electrician when I got a message on LinkedIn which landed me my job as a developer.
I'm also not above admitting that we make too damn much compared to our peers who do jobs which actually contribute to society (teachers like my wife or electricians like my friend). But I'm gonna ride the wave, try to max my salary, and try to encourage our son to not discard jobs like electricians, carpentery, etc.
I had to try hard (not in terms of actual work, because that's not what makes others pay you) to get enough of a hike, that increasing milk prices would not make me unable to buy it.
Linkedin has never given me any good connections. I've had my account for years and post from time to time. Looking for jobs on them. Just tryna get an entry level job but haven't heard anything from anyone.
I don't want anyone around me knowing how much money make, because they would definitely look at, and treat me differently. I came from the hood, I'm still that person at heart, despite making a really good money for once in my life.
