In Finland, everyone's taxable income is a matter of public record. One theoretical benefit of such a policy is that it eliminates information asymmetries between workers and employers in wage bargaining.
If it were opt-in that would be fine, otherwise it's an invasion of privacy of most people who aren't rich.
It's almost as bad as having medical conditions and STIs test results listed publicly.
Facilitating public exposure of counting other people's money doesn't help anyone except the rich to know if you can fight them in court or how much to bribe them.
Fight wealth inequality with income-&-holdings-proportional fines; simple, government-calculated graduated taxes without complicated exemptions; elimination of corporate/wealth welfare; and expand economic-advancement-oriented welfare to those who aren't super-rich who can use it.
