It does not suffice.
We mostly do have this data in the US and wealth inequality keeps deepening.
The only purpose of the salary taboo is to keep rich people rich.
While it is part of the motivation, calling it the only purpose is just hilariously wrong, completely lacks any nuance/empathy, and a single case of something existing outside of the "only purpose" statement proves it wrong immediately.
My brother ex-communicated my dad because he wouldn't stop hounding him for money. My brother became wealthy at a young age, and made the unfortunate mistake of divulging his finances to my narcissistic father. My father made terrible financial decisions in his life and subsists entirely on social security. He also bragged routinely about cheating on my mom, who got the courage to pull us out of that situation when we were kids. Any extra money I have would go to my mom, not my piece of crap dad.
I can't imagine how terrible it would be if he simply knew how much money I make.
This is the "lacking in nuance" thing that parent was talking about.
Salary transparency can help individuals by revealing their unfair pay relative to their peers. Correcting such injustices are not big money overall, they're not going to create meaningful wealth distribution, it's not going to make the rich noticeably less rich.
That being said I'm well aware of how load bearing "somehow thoroughly universalized" is in my statement. Perhaps it's only possible in a culture that truly rejects secret keeping as deeply harmful from an individual level up. I don't believe we can get there from here anytime soon, and if we tried it would just be another system for the people who figure out how to keep secrets to exploit that info asymmetry. In a world of cooperating actors though . . . yeah, I know I'm dreaming.
Why should we avoid it? Oh, I know a few arguments and they're compelling in abstract but are inevitably just arguments towards a reshuffling of who or what has power. Power over another, however you want to define it, is inherent in hierarchical structures, and I am sorry to say but hierarchies - that is, rankings of entities - are one of the most fundamental aspects of all known existence. How many electrons do you have?
I get where you're coming from. We should avoid concentration of power in human societies because this always (at least so far) leads to abuse of that power.
However, reality exists.
Hierarchies are unavoidable and useful.
I'm more making the argument that cultural disgust at concentration of power, and a general erring on the side of flatness whenever we can would go a long way toward a healthier society.
All law, court cases, contracts, and legally binding agreements being public? I could be convinced that's a good idea. Bright sunlight from all angles would revel inequity and could allow better civic planning and civil action (voting).
I think the line should be drawn a little in favor of being private, and in favor of hiding non-recurring purchases for personal use. It would be more harmful than good to reveal where and when someone gets food, takes a vacation, etc.
I imagine that publishing everybodies income would not have a significant impact on freedom even if some people would prefer to keep that data private.
Universal Declaration of Human Rights (Article 12)
International Covenant on Civil and Political Rights (Article 17)
I imagine that this policy also helps with keeping the flat distribution, since people will know when someone is making more money and will request similar salary increases.
skatteentaten.no also lists a bunch of other privacy restrictions that they have in place.
This was, in part, to discourage criminals using the database to target wealthy people, and to curtail some of the harassment that resulted from this information being brought to light. This change apparently was a enough to dissuade the majority of usage, as most people now apparently just search for themselves.
Thanks for the data though.
I told my dad what I made, he messed up and told my mom, my mom told her brother and now this guy I haven't seen in a couple of decades is begging me for money.
He showed up at my house once to beg and then got mad because he had spent the last of his money on gas to drive to my house to ask for money.
Cut toxic people out of your life!
https://www.reddit.com/r/raisedbynarcissists/ is even more relevant than that.
It doesn't fight against tax evasion or anything, because the wealthy of the world will have yet another incentive to mask their income / assets through any of the number of mechanisms currently available.
If you want pay transparency to fight pay inequality, then anonymized pay based on role / job title should suffice.
Any legitimate need for such information can either be obtained through asking, or through the courts. At least then, I have a say in the matter and a right to defend myself in cases where I believe it necessary.
People are entitled to privacy. I wouldn't want random people knowing my salary anymore than I'd want them knowing what medications I take.
