I have to hard disagree here. There are a lot of bad actors and abusive/manipulative people who would use this information to unfairly pressure someone if they knew how exactly much they made.
If they had the ability to pressure someone, why would they not simply be able to press them to show them their tax returns? And would this happen with sufficient frequency to negate the benefits of price transparency?
Norway has had public tax returns for a long time.
Does anyone who lives in a country where tax records are already public have any insight on whether this happens with any non-pro-corporate-fearmongering frequency in those places?
